/*
|
|
* There are three Mesa datatypes which are meant to be used by device
|
|
* drivers:
|
|
* GLcontext: this contains the Mesa rendering state
|
|
* GLvisual: this describes the color buffer (rgb vs. ci), whether
|
|
* or not there's a depth buffer, stencil buffer, etc.
|
|
* GLframebuffer: contains pointers to the depth buffer, stencil
|
|
* buffer, accum buffer and alpha buffers.
|
|
*
|
|
* These types should be encapsulated by corresponding device driver
|
|
* datatypes. See xmesa.h and xmesaP.h for an example.
|
|
*
|
|
* In OOP terms, GLcontext, GLvisual, and GLframebuffer are base classes
|
|
* which the device driver must derive from.
|
|
*
|
|
* The following functions create and destroy these datatypes.
