a5cdfdfd87 [cogl-offscreen] Cleans up the cogl offscreen API and adds documentation
There were several functions I believe no one is currently using that were
only implemented in the GL backend (cogl_offscreen_blit_region and
cogl_offscreen_blit) that have simply been removed so we have a chance to
think about design later with a real use case.

There was one nonsense function (cogl_offscreen_new_multisample) that
sounded exciting but in all cases it just returned COGL_INVALID_HANDLE
(though at least for GL it checked for multisampling support first!?)
it has also been removed.

The MASK draw buffer type has been removed. If we want to expose color
masking later then I think it at least would be nicer to have the mask be a
property that can be set on any draw buffer.

The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes
have been moved up into cogl.h since they are for managing global Cogl state
and not for modifying or creating the actual offscreen buffers.

This also documents the API so for example desiphering the semantics of
cogl_offscreen_new_to_texture() should be a bit easier now.

e47b198225 add cogl_push_draw_buffer() and cogl_pop_draw_buffer()
These are necessary if nesting redirections to an fbo,
otherwise there's no way to know how to restore
previous state.

glPushAttrib(GL_COLOR_BUFFER_BIT) would save draw buffer
state, but also saves a lot of other stuff, and
cogl_draw_buffer() relies on knowing about all draw
buffer state changes. So we have to implement a
draw buffer stack ourselves.

f85377372c [cogl] Updates all file headers and removes lots of trailing white space
Adds missing notices, and ensures all the notices are consistent. The Cogl
blurb also now reads:

 * Cogl
 *
 * An object oriented GL/GLES Abstraction/Utility Layer
