Functions
static SInt32	gml_Rect_Width (gml_TRect *rect)
	Return the width of a gml_TRect.
static SInt32	gml_Rect_Height (gml_TRect *rect)
	Return the height of a gml_TRect.
static gml_TBoolean	gml_Rect_Equal (gml_TRect rect0, gml_TRect rect1)
	Return true iff the two rectangles are identical.
static void	gml_SetValidRect (SInt32 w, SInt32 h, gml_TRect rectPtr, gml_TRect validRect)
	If rectPtr is NULL, set validRect to the (0, 0, w, h) rectangle.

static void gml_SetValidRect	(	SInt32	w,
		SInt32	h,
		gml_TRect *	rectPtr,
		gml_TRect *	validRect
	)			`[inline, static]`

If rectPtr is NULL, set validRect to the (0, 0, w, h) rectangle.

Else set it to the intersection of that rectangle and the rectangle pointed by rectPtr.
