+ * \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:
+ * - 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.
