// XaDraw is an abstraction layer for GDraw V3. The abstraction layer
// compiles away leaving the program calling GDraw directly if CONFIG_DEBUG_XADRAW
// is not defined. If CONFIG_DEBUG_XADRAW is defined all calls to GDraw go via debug
// wrapper functions. The wrapper functions currently display the name of each
// function as it is called and displays the value of the pointer to the context.
// The context pointer and function name can be used to determine which call failed
// and what the current stack pointer is if a call to GDraw crashes.

// To use the abstraction layer simply replace all calls to GDraw with the
// appropriate Xa name. See conversion table below:
//
// GDraw V3 interface.
//
// GDraw_      -> XaDraw_
// GColour_    -> XaColour_
// GBitmap_    -> XaBitmap_
// G3D_        -> Xa3D_

// Include the Oil specific version of GDraw
//#include "xadrwoil.h"
#include "xagdraw.h"

// If CONFIG_DEBUG_XADRAW is defined then declare a structure that contains pointers to
// all the GDraw functions. These are used to implemented the debugging functionality
// by inserting an additional layer between camelot and GDraw. See GDraw for more
// information about the individual GDraw functions.
