OpenGL texture format

[visinoz]

Hello,

Would it be possible for us to specify the texture's format for loading pictures? That way, we could optimize memory depending on our pictures format (I'm using 8 bits picture, so I could save a lot of memory using another format than RGBA8).

Something like love.graphics.setTextureFormat(TextureFormat) would be nice (where TextureFormat could be a string representing the format).

Ex.:
love.graphics.setTextureFormat('RGBA8') -- would be the default format
love.graphics.setTextureFormat('RGBA2') -- what i would probably use for my 8 bits image i guess
etc

Thanks for your great engine!

The idea has potential, though I personally wouldn't endorse this particular implementation (not that I'm in a position to endorse anything...). Perhaps as an extra optional param to love.graphics.newImage(..)? or maybe Image:setPixelFormat(fmt)?
I'm also concerned about exposing too much of the underlying implementation here, though careful choice of the format identifiers should solve that.
