(graphics/R-rgl) Updated 0.107.14 to 1.0.1

# rgl 1.0.1

## Major changes

* The long promised deprecations of the `rgl.*` functions
have happened.  Now deprecated: `rgl.abclines`,
`rgl.bbox`, `rgl.bg`, `rgl.clear`, `rgl.clipplanes`,
`rgl.close`, `rgl.light`, `rgl.lines`,
`rgl.linestrips`, `rgl.material`,  `rgl.open`,
`rgl.planes`, `rgl.points`, `rgl.quads`,
`rgl.select3d`, `rgl.set`, `rgl.setAxisCallback`,
`rgl.sprites`, `rgl.surface`, `rgl.texts`,
`rgl.triangles`, and `rgl.viewpoint`.
* A vignette "Deprecating the `rgl.*` interface"
has been added.
* Also deprecated: `elementId2Prefix`, `writeWebGL`

## Minor changes

* Since `rgl.material` is deprecated and no
longer contains the list of material types in its
argument list, `rgl.material.names` and `rgl.material.readonly` have been
added.
* Similarly, `rgl.par3d.names` and `rgl.par3d.readonly`
contain lists of properties that may be set or queried
in `par3d()`.
* The flexibility improvements for `surface3d()` in
0.111.6 were incomplete.
* Argument `flip` has been added to `surface3d()` to allow
front and back to be switched.

# rgl 0.111.6

## Minor changes

* Added a panning example to the help page for `setUserCallbacks()`.
* Replaced all calls to `sprintf` from C/C++ code with calls to
`snprintf`.
* `surface3d` and `rgl.surface` are now more flexible,
allowing any of the 3 coordinates to be a vector or matrix
as long as at least one is a matrix.
* `material3d` can now specify an `id` to query properties
for individual objects.
* Since `rgl.material` is soon to be deprecated and no
longer contain the list of material types in its
argument list, `rgl.material.names` and `rgl.material.readonly` have been
added.
* Similarly, `rgl.par3d.names` and `rgl.par3d.readonly`
contain lists of properties that may be set or queried
in `par3d()`.
* Made some examples conditional on interactive use
to save time on CRAN.

## Bug fixes

* Default mouse modes used when a window is opened by an `rgl.*`
call (which is not recommended!) now match
the defaults in `rgl::r3dDefaults`.
* Missing values could cause `surface3d()` to segfault.
* The C source code for `gl2psGetFileFormat` missed declaring
a prototype.

# rgl 0.110.2

## Major changes

* Material property `"blend"` has been added, to allow
various kinds of blending for semi-transparent objects
(issue #245).

## Minor changes

* The `Buffer` object now handles reading of sparse
accessors.
* Low level drawing of primitives has been made more
memory efficient.  This is only likely to make a
noticeable change with very large objects, where R
was running out of memory because of unnecessary
duplication. (Related to issue #260.)
* Recycling of x, y and z vectors in several functions
is more consistent.
* The `polygon3d()` function now chooses coordinates
automatically, as `triangulate()` does (PR #262.)
* The `mtext3d()` and related functions such as
`title3d()` now accept language objects
other than expressions, as `plotmath3d()` always has
(issue #273).

## Bug fixes

* The bounding box could be calculated incorrectly
if data all had large values (issue #250).
* Shiny displays failed to load the shaders (issue #249).
* `transform3d()` failed due to missing argument (issue #253).
* `readOBJ()` is now more flexible in what kinds of
separators it will accept. (issue #258).
* Failure to initialize could cause a segfault.
* On non-macOS platforms, gray-scale textures failed
to display, with a message about an invalid enumerant.
* The third coordinate for `adj` that was added in 0.108.3
was not rendered properly in `rglwidget()` displays of
text.  This sometimes caused text to disappear when it
was near the far limit of the display (issue #269).
* The X11 error fix in 0.109.6 could result in R
freezing in `Rcmdr`.
* Low level drawing functions are now more consistent
about returning an invisible `NULL` if asked to plot zero
items, rather than raising an error or crashing (issue #274).
* Calling `axis3d()` with no ticks or labels no longer triggers
an error, it now silently returns `NULL`.

# rgl  0.109.6

## Minor changes

* `rglwidget()` displays now act on "pointer" events,
not just "mouse" events, so they should be more usable
on touch screens and tablets (PR #240).

## Bug fixes

* Plotting `scene3d()` objects didn't handle suppressed
axes properly, drawing the default axis instead (issue
#241).
* On some systems using X11, `rgl` would segfault when
the "fixed" font was not found.
* X11 errors could cause R to abort.

# rgl  0.109.2

## Major changes

* Changes to support glTF animation:
  - Handling of `embedding = "modify"` for the model matrix
    has changed.  Now the centering step is only done for
    `embedding = "replace"`.  In addition, various bugs
    have been fixed.
  - If a subscene has no lights defined, the lights from the parent
    are used.
  - `plot.rglscene()` now ends with the root subscene as
    current.  It also allows specification of `open3d()`
    parameters in a list.
  - The `MATn` types in `Buffer` are returned as arrays with
    dim `c(n, n, count)`.
  - The `plot3d.rglscene` method now passes `...` to `open3d()`.
  - The `setUserShaders()` function now allows arrays of 4x4 matrices as \ 
"uniforms", and allows additional textures to be specified.
* `sprites3d()` now has the option of
`rotating = TRUE`, to allow 3D sprites to rotate with
the scene.
* Added `getShaders()` function to get shaders used in WebGL.
* Now detects if `rgl` is running within `reprex::reprex()`
and if so arranges that a screenshot will be included in the
output.
* Added default shaders to be used in `rglwidget()`, rather than
constructing them on the fly.  This incompatibly affects the use
of lights and clipping planes with user shaders:  their data
is now stored in arrays rather than multiple numbered variables.

## Minor changes

* Now that `pkgdown` 2.0.0 has been released, a number
of internal workarounds to support the development version
have been removed.
* Added `as.mesh3d()` methods for `"rglsubscene"` and \ 
`"rglscene"`.
* `open3d()` now handles `useNULL` and `silent` arguments
passed in `params`.
* Controls passed to `playwidget()` may now include a
component specifying HTML dependencies.
* Added `rglwidgetClass.readAccessor()` method to let other
code use the buffering.
* Changed the internal organization of bounding box calculations.
* All functions that produce meshes now accept
material properties.  Newly modified to do so using the `...`
argument:  `cylinder3d()`, and `getBoundary3d()`.
* Updated the system requirements and installation instructions.
* Solid bounding box decorations now try harder to display 3 faces (issue #206).
* Now that `webshot2` is on CRAN, instructions for
installing it from Github have been removed.
* Sometimes `webshot2` snapshots are very slow, so
the default for the `webshot` argument to `snapshot3d()`
now depends on the `RGL_USE_WEBSHOT` environment
variable, using `TRUE` if it is unset. (Reported by Prof. B. D. Ripley.)
* If the Chrome browser is not found, `snapshot3d(webshot = TRUE)` now issues a \ 
warning and
reverts to using `rgl.snapshot()`.
* Buffers now use "normalized integers" to store
color or texture coordinate values that lie between 0
and 1 when it saves some space.
* At the request of CRAN, the `akima` package is no
longer suggested.

## Bug fixes

* `as.mesh3d.rglobject()` didn't handle objects with indices
properly.
* In WebGL, the front vs back calculation sometimes
got the wrong result (issue #164).
* `pop3d(tag = x)` did not always find the objects with `tag == x` if they were \ 
not in the current subscene.
* The default values for `front` and `back` in `rgl.material`
and `material3d` are now `"filled"`, as documented in some
places.
* The `fog` setting wasn't handled properly by `bg3d()`.
* Numerous cases of partial argument matching were fixed
(suggestion of Henrik Bengtsson in issue #170.)
* Argument `col` is accepted as a synonym for `color` in `material3d()` and \ 
`rgl.material()`.
* `planes3d()` objects were not displayed consistently
in `rgl` windows and WebGL displays, because the bounding
boxes were not computed consistently (issue #169).
* Some initialization wasn't done properly in Shiny apps,
so they failed after a redraw (issue #173).
* Buffers are now optional, as they don't work with
Shiny scene changes (also issue #173).
* The NULL device would sometimes miscalculate the
bounding box.
* `selectpoints3d(closest = TRUE)` selected too many points
when multiple objects were in the scene.
* Clearing nested subscenes could cause a segfault and crash.
* In `knitr` and `rmarkdown`, blank plots could be shown
when `par3d(skipRedraw=TRUE)` was set (issue #188).
* Objects drawn with `sprites3d()` weren't lit correctly
in WebGL (issue #189).
* Objects with textures were sometimes drawn more than once, both
before the texture loaded and after.  This was most noticeable for
objects with user textures.
* Axis mode `"pretty"` got lost when scenes were redrawn.
* Tick labels were sometimes lost in WebGL displays and
`snapshot3d()` results (issue #197).
* The new material properties from 0.107.10 and 0.108.3
were not handled properly by `plotmath3d()`.
* `rglMouse()` did not set the default value of the drop-down
selector properly (issue #213).
* `merge.mesh3d()`, used by `filledContour3d()`, didn't handle
colors properly (issue #212).
* `bg3d(sphere = TRUE)` has been fixed (issue #207).
* Textures were not appearing on spheres, and front-back
differences weren't being rendered (issue #217).
* When "knitting" within RStudio under R 4.2.0 on
Windows, `rgl` scenes didn't appear (reported by
Dieter Menne.) A workaround has been added.
* In `rglwidget()`, axis labels were not always
displayed, and did not move with solid bounding box
decorations properly (issue #206).
* On some systems, `lines3d()` using both missing values
and transparency did not draw properly (issue #234,
originally reported by Gaspar Jekely).
* The `rglShared()` example failed when `crosstalk`
was uninstalled.

# rgl  0.108.3.2

## Bug fixes

* Changes introduced in 0.100.50 lacked checks; these caused
segfaults in Windows with R 4.2.0 and RStudio (issue #208).
* A typo caused problems loading fonts on some systems.

# rgl  0.108.3

## Major changes

* Added `getBoundary3d()` function to extract the boundary
edges of a mesh.
* Added material property `tag`, a string associated
with each object.  The value is reported by `ids3d(tags = TRUE)` and
may be used to select objects in most functions that use ids,
but otherwise is
largely ignored by `rgl`.  The `tagged3d()` function returns
information on tags.
* Primitive types (points, lines, segments, triangles, quads)
can now accept an `indices` parameter, similar to the
indices in `mesh3d` objects.
* Added `Buffer` object, based on glTF design, for holding binary
data for `rglwidget()`.

## Minor changes

* Allowed for a third coordinate in `text3d()`'s `adj`
parameter.
* Added support for `adj`, `pos` and `offset` to
`sprites3d()`.
* Added support for `pos` values of `0` (at specified
location), `5` (in front of it), and `6` (behind it) in
`text3d()`, `sprites3d()` and `plotmath3d()`.
* `crosstalk` is now a Suggested package, rather than
a required one.
* The `Makevars.ucrt` file has been modified with
contributions from Tomas Kalibera to work with his `winutf8`
build of R.
* `bgplot3d()` no longer pauses for each page when running
examples.
* `deldir` version 1.0-2 is incompatible with `rgl`.  Added
the `checkDeldir()` function to avoid running it.
* `shade3d()` treated texture coordinates like colors, and
  duplicated the first one for the whole face when `meshColor = \ 
"faces"` was chosen.
  Instead, they are now treated like vertex coordinates.
  (Reported by Michael Sumner in issue #145).
* Corrected the documentation and made the implementations
of `asHomogeneous()`, `asEuclidean()` etc. more consistent.
* An `as.rglscene()` generic has been added, though no methods
are defined in this package.
* `downlit` 0.4.0 has been released with support for `rgl`, so instructions
for installing the devel version have been removed.

## Bug fixes

* Fixed rendering of text as sprites3d() objects.
* Added `--static` flag to configure script for FreeType
  installation.  (Suggestion of Simon Urbanek and Prof. Brian Ripley.)
* `shade3d()`, `wire3d()` and `dots3d()` overrode
  `"front"` and `"back"` material settings in mesh objects.
* `rglwidget()` handling of bounding box decorations had
  several bugs.
* `rgl` could not find routines in the DLL on some Windows
installs (Issue 148.)
* Some cases where allocations were not protected have been fixed.
