-/**
- * \file context.h
- * Mesa context and visual-related functions.
- *
- * There are three large Mesa data types/classes which are meant to be
- * used by device drivers:
- * - struct gl_context: this contains the Mesa rendering state
- * - struct gl_config: this describes the color buffer (RGB vs. ci), whether
- * or not there's a depth buffer, stencil buffer, etc.
- * - struct gl_framebuffer: 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, struct gl_context, struct gl_config, and struct gl_framebuffer
- * are base classes which the device driver must derive from.
- *
- * The following functions create and destroy these data types.
