-/**
- * \file context.h
- * Mesa context/visual/framebuffer management functions.
- *
- * There are three Mesa data types 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
- * data types. 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 data types.
