Summary: OpenGL fixes

Initial Comment:
Fixed: 
1. Black borders
2. Bottom line
3. Vertical black line
4. 320x240 games (no aspect change possible)
5. Switching to GL mode corrected (Bilinear Filter
activation).
6. Added more comments for better understanding.

Comments:
1. if you want to ditch the code, no problem.
2. FB2GL_320 when set would use 2 textures. If not set
then would just use one texture (256x256).
3. I am still going to add the option to use one
512x256 texture (modern 3d video cards). 320x256
texture I think will not work.
4. The vertical black line is caused by a gap between
the two textures (256x256). See the variable
texture1_end (fb2opengl.h)
5. blit16() is just for ScummVM, and needs the flag
FB2GL_NO_320. The other flags may not work with this
method. For non-scummvm use update().
