OPENGL: Introduce abstraction for framebuffer.
...
This allows us to use various framebuffer settings easily. Now the GPU
accelerated CLUT8 surface implementation does not need to query former
framebuffer state anymore.

OPENGL: Detect NPOT support for GLES.
...
For GLES1+ there exists GL_OES_texture_npot, which indicates that there is
NPOT support.
GLES2 always had (limited) NPOT support, which is all we require, thus we
always enable it.

OPENGL: Handle GLES2 and GL shaders uniformly.
...
GLES2 requires precision qualifiers to be set and allows use of precision
qualifiers. For GLES2 we define a default precision now. Since precision
qualifiers are not supported in the GLSL version we use for GL, we
introduce compatibility #defines.

OPENGL: Introduce simple abstraction for surfaces.
...
This is basically an interface extracted from Texture without any knowledge
about any actual implementation, except for copyRectToTexture, fill, and
dirty rect handling. These are convenient helpers.

OPENGL: Support RGB555 for OpenGL ES output.

This mode should *not* be used by any new engines/code. If someone is going
to use it and says it works with the OpenGL output, please make them wear a
red uniform and beam them onto a remote planet.

OPENGL: Allow runtime specification of OpenGL mode.
...
Formerly, we required that the OpenGL mode was fixed at compile time. Now we
allow the code to work with whatever it is given at runtime.
It is still possible to force a context type on compile time.
