- * Device Driver (DD) interface
- *
- *
- * All device driver functions are accessed through pointers in the
- * dd_function_table struct (defined below) which is stored in the GLcontext
- * struct. Since the device driver is strictly accessed trough a table of
- * function pointers we can:
- * 1. switch between a number of different device drivers at runtime.
- * 2. use optimized functions dependant on current rendering state or
- * frame buffer configuration.
- *
- * The function pointers in the dd_function_table struct are divided into
- * two groups: mandatory and optional.
- * Mandatory functions have to be implemented by every device driver.
- * Optional functions may or may not be implemented by the device driver.
- * The optional functions provide ways to take advantage of special hardware
- * or optimized algorithms.
- *
- * The function pointers in the dd_function_table struct should first be
- * initialized in the driver's "MakeCurrent" function. The "MakeCurrent"
- * function is a little different in each device driver. See the X/Mesa,
- * GLX, or OS/Mesa drivers for examples.
- *
- * Later, Mesa may call the dd_function_table's UpdateState() function.
- * This function should initialize the dd_function_table's pointers again.
- * The UpdateState() function is called whenever the core (GL) rendering
- * state is changed in a way which may effect rasterization. For example,
- * the TriangleFunc() pointer may have to point to different functions
- * depending on whether smooth or flat shading is enabled.
- *
- * Note that the first argument to every device driver function is a
- * GLcontext *. In turn, the GLcontext->DriverCtx pointer points to
- * the driver-specific context struct. See the X/Mesa or OS/Mesa interface
- * for an example.
- *
- * For more information about writing a device driver see the ddsample.c
- * file and other device drivers (X/xmesa[1234].c, OSMesa/osmesa.c, etc)
- * for examples.
- *
- *
- * Look below in the dd_function_table struct definition for descriptions
- * of each device driver function.
- *
- *
- * In the future more function pointers may be added for glReadPixels
- * glCopyPixels, etc.
- *
- *
- * Notes:
- * ------
- * RGBA = red/green/blue/alpha
- * CI = color index (color mapped mode)
- * mono = all pixels have the same color or index
- *
- * The write_ functions all take an array of mask flags which indicate
- * whether or not the pixel should be written. One special case exists
- * in the write_color_span function: if the mask array is NULL, then
- * draw all pixels. This is an optimization used for glDrawPixels().
- *
- * IN ALL CASES:
- * X coordinates start at 0 at the left and increase to the right
- * Y coordinates start at 0 at the bottom and increase upward
- *
