* 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.
+ * - 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.
