Log message:
emulators/retroarch: Update to 1.7.6

pkgsrc specific changes:

* Remove the deprecated and broken libxml2 and libusb1 options.
* Fix the qt5 option.
* No longer depends on libretro-glsl-shaders, instead use the built-in
updater to install shaders. Fixes shader preset saving as non-root...
* I submitted a sun audio driver to upstream and they accepted it, so
NetBSD and (probably) SunOS will now default to "audioio" instead of \ 
"oss".

Log message:
libretro-glsl-shaders: Make do-install more portable.

Log message:
Simplify retroarch packagaing by removing retroarch-assets.

Switch to a bundled release for the assets, and make libretro-database
and glsls-headers current. This will make it easier to update versions
between releses where the database compatibility differs (e.g. for fbalpha)

Log message:
emulators/libretro-glsl-shaders: Use RETROARCH_VERSION and set HOMEPAGE.

Log message:
libretro-glsl-shaders: Import libretro-glsl-shaders-1.7.3.

Shaders and filters can be applied to video games to achieve some kind of
visual effect. These can be from attempting to replicate CRT displays, RF
cables, smooth scaling and anti-aliasing, or something more exotic.

This package contains the shaders provided by the libretro project for use
with RetroArch (where .glsl and .glslp shaders are supported out of the box).

They could also in theory be used with other OpenGL programs.

For more information, including examples of specific shaders, see the
Emulation General wiki:
