Log Message:
(graphics/R-rgl) Updated 1.0.1 to 1.3.14

# rgl 1.3.14

## Minor changes

* `rgl.incrementID()` has been added.
* An example using log axes has been added to the
help page for `axes3d()`.

## Bug fixes

* `clear3d("all")`, calling `bg3d()` on the root
subscene, and some cases of `pop3d()` involving the
background could create a leak of a background object
(issue #439).  For back compatibility of saved results, these cases
still increment the object ID number, but don't
actually create a new object.
* `rglwidget()` displays didn't support objects with
`smooth = FALSE`.

# rgl 1.3.12

## Minor changes

* `readSTL()` can now read (some) ASCII format STL files.
* The configure script has had minor changes, and autoconf
support files have been updated.
* `uname` is no longer used during startup (PR #435
submitted by Jonathon Love).

## Bug fixes

* Background plots did not always appear (issue #421).
* Changing the background resulted in an additional background
object instead of replacing the current one.
* Colors weren't handled correctly by `writePLY()` (issue #425).
* `bbox3d()` objects ignored the `xlen`, `ylen` and `zlen`
settings when rendered using `rglwidget()` (issue #415).
* In certain cases, the `WebGL` vignette started with the
mouse mode set to "selecting".
* The `rglwidget()` function gets a new argument `fastTransparency`
which makes WebGL mimic the `rgl` device when drawing transparent
objects.  The default value is `TRUE` unless option
`rgl.fastTransparency` is set to `FALSE`.
* `writeSTL()` now writes `endsolid`, which is required by some apps.

# rgl 1.3.1

## Major changes

* `sprites3d()` now supports plotting different 3D symbols
at each location (issue #406).

## Minor changes

* ARIA support now declares `rgl` scenes with `role = "img"`.
* The vignettes in this package now use
`markdown::html_format`, so they no longer require Pandoc
(though Pandoc-using output formats like `html_document` will still be supported).
*  Christophe Geuzaine's GL2PS library (used by `rgl.postscript()`)
   updated to version 1.4.2, and blending (transparency)
   has been enabled in formats that support it.
*  The `Makevars.ucrt` file has been changed for compatibility
   with an upcoming change to Windows Rtools. (Pull request #412 submitted by \ 
Tomas Kalibera).

## Bug fixes

* The ARIA support caused `htmlwidgets::saveWidget()` to fail when
run in a Shiny session.
* `text3d()` and `mtext3d()` did not pass the `cex` argument to
`plotmath3d()` (pull request #384).
* `polygon3d()` failed when given exactly 3 points (issue #388).
* `snapshot3d()` failed on Windows with some versions of `webshot2` (issue #391).
* Fixed issues caused by misuse of `dev.off()` using new function
`safe.dev.off()`.
* Fixed issue with `warning()` call reported by CRAN.
* Smooth shapes were not rendered correctly by `rglwidget()`.
  This was especially noticeable for spheres with `fov = 0`, but was present in \ 
other cases as well (issue #401).
* `textype = "alpha"` was not rendered correctly by `rglwidget()` \ 
(issue #408).
* `setUserCallbacks()` and related functions failed when
the `subscene` argument was anything other than the root
subscene.

# rgl 1.2.1

## Major changes

* Support for non-PNG textures has been added.  Currently
supported:  JPEG files and any other object
for which `grDevices::as.raster()` works, e.g. matrices.
(Fixes issue #196.)

## Minor changes

* Support for "alt" text has been added to `rglwidget()`.
Full support in R Markdown or `knitr` requires a `knitr` update
to version 1.42.12 or newer.
* Some of the tests have been relaxed slightly so they
shouldn't trigger errors on the M1Mac test platform.
* Internally, the C++ code has dropped the use of the internally
defined `String` type, settling on `std::string` instead.
* `subdivision3d()`, `clipMesh3d()` and related functions now
(optionally) record the original faces associated with each new one
in a `mesh$tags` addition to the output.

## Bug fixes

* The `Makevars.win` file was being produced incorrectly on
older Windows versions.
* `rgl.window2user()` did not work correctly when multiple panes
were showing.  This caused `arrow3d()` to fail in some panes
(issue #354).
* `selectpoints3d()` had a typo which was revealed by
warnings in recent R versions.
* `getShaders()` was broken in 1.1.3.
* `arc3d()` can now handle "arcs" that are straight lines along
a radius (issue #357).
* Spheres did not show textures correctly (issue #360).
* `hover3d()` failed to display default labels in R (issue #362).
* `shade3d()` didn't handle meshes with a mix of triangles and
quads properly when `meshColor == "faces"`.
* `subdivision3d()` and related functions now handle colors
properly.
* `addNormals()` sometimes gave `NaN` values due to rounding
error (issue #372).
* `arc3d()` sometimes missed plotting the last segment of the arc (issue #369).
* `R_NO_REMAP` has been defined and header includes have been
rearranged to prevent conflict between R internals and C++17
library.  (Thanks to Prof. B. D. Ripley and G. Csardi for
suggested fixes.)

# rgl 1.1.3

## Major changes

* A new function `hover3d()` has been added to display
"hover hints":  labels next to points when the mouse
passes near them.
* A new material property `"texmode"` has been added
to control how textures are applied.  The default is `"modulate"`,
consistent with previous versions.  If set to `"replace"`,
the texture is displayed without any lighting effects or dependence
on the original color of the surface.
* Many of the demos have been moved to a new vignette called
`demos`.
* `rgl` now uses the `glad` loader which will eventually allow
access to newer OpenGL functions in systems that support them.

## Minor changes

* The `texenvmap = TRUE` material property is now supported
in WebGL.
* The method of including shader source code
has changed to work around a limitation in Jupyter.
* The default C++ standard is now accepted, rather
than requiring C++11.  On R versions prior to R 4.2.0
C++11 is still requested.

## Bug fixes

* The `as.mesh3d.rglId()` and `as.triangles3d.rglId()` methods
and the `selectpoints3d()`, `writeOBJ()`, `writePLY()`
and `writeSTL()`
functions did not handle indices
in the objects they were processing (issue #293).
* Transparent planes were not always drawn properly
in WebGL (issue #300).
* `view3d()` now returns a `lowlevel()` result so that
it will be handled properly in WebGL vignettes with
auto printing.
* If `transform3d()` or `rotate3d()` changed the orientation
of a `mesh3d` object with normals, the normals ended up
with the wrong sign. (Reported by Stephane Laurent.)
* `scene3d()` (and hence `rglwidget()`) did not save
the normals for unlit objects.  When the objects were
also indexed, this prevented proper calculation of
front and back.  This is fixed, and a warning is
issued if normals are not provided when needed.
* It was possible to call `glVersion` before OpenGL was
initialized; this resulted in a segfault with the new
`glad` loader, and may have been the cause of some older crashes
as well.  This has been fixed.
* `readOBJ()` did not handle comments properly.
* Sprites consisting only of line segments (as used
for example by `pch3d()`) caused rendering to fail in
`rglwidget()` (issue #316).
* Headers have been cleaned up to fix problems
identified by Rtools43.
