#15499: TINYGL: Support paletted textures
------------------------+---------------------------
Reporter:  ccawley2011  |      Owner:  (none)
    Type:  defect       |     Status:  new
Priority:  normal       |  Component:  Graphics
 Version:               |   Keywords:  tinygl memory

------------------------+---------------------------
 Both Grim Fandango and The Longest Journey use textures with palettes,
 however since TinyGL doesn't currently support those, they're converted to
 true colour before uploading them.

 There are a couple of different OpenGL extensions that could be used as a
 basis for adding TinyGL support:
 -
 https://registry.khronos.org/OpenGL/extensions/EXT/EXT_paletted_texture.txt
 -
