I've never heard of those things.

Mesa is an implementation of OpenGL and has no functions for 
reading/writing image files whatsoever.

Typically, a utility library is used to read/decompress an image file 
into a malloc'd block of memory.  That memory/image can then be handed 
to OpenGL via glTexImage, or glDrawPixels, etc. for rendering/drawing.

If you're working with jpegs, I suspect libjpeg is being used.
