According to wikipedia [1], it is part of OpenGL 1.3. Isn't it
suficient (IANAL)?
Also, S2TC seem patent-free and S3TC compatible [2]

Didn't knew about this. I will move to that then.

Some advance in this area (some glitches fixed). Costumes a still
garbage (because they are written in 8bit).

We already have a modular way to load sounds (flac, ogg, ...). ffmpeg
has "-acodec adpcm_ima_wav".

As much as possible, I try to move the SE specific code in the se
folder (I can make an se folder in the imuse folder too).

They are shaders, and this is not a must-have.

My work is on the non-Steam PC DVD. I thought that those games were
abandonware because it was hard to get them (and I'm still waiting for
MI2SE). I now know that this is not the case on iOS, Xbox and Steam.
