ANDROID: Don't use compressed textures for the game screen
Some GLES drivers suck so much that uploading data to the GPU takes
ages. CLUT8 games now use a faked paletted texture, which internally
uses a RGB565 hardware texture (Android's native pixel format).
This seems to be the only way to efficiently implement constant
changing textures with GLES1 - at the cost of extra buffers.
Then again, we can now use glTexSubImage2D to only update the dirty
rects, which wasn't possible before because glCompressedTexSubImage2D
is only usable on GLES2. This commit does exactly that.
Overall, the CPU usage is massively reduced for CLUT8 games.
