Re-org of gl_pixel_attrib struct.

Reorder fields according to the order in which the pixel transfer operations
take place.  Improve comments.
Move the pixel maps out of gl_pixel_attrib since they're not supposed to be
pushed/popped by glPush/PopAttrib.
New gl_pixelmap and gl_pixelmaps structs to contain the pixelmaps.
