Data Fields
u32	conversion
	Conversion to perform when converting pixels to lower bit precision. More...
u32	format
	Format of source image pixels. More...
u32	operation
	Blit operation. More...
s16	clipX
	X origin of clipping rectangle, within the destination surface.
s16	clipY
	Y origin of clipping rectangle, within the destination surface.
u16	clipW
	Width of clipping rectangle, within the destination surface.
u16	clipH
	Height of clipping rectangle, within the destination surface.
s16	outX
	X origin of destination rectangle.
s16	outY
	Y origin of destination rectangle.
u16	outW
	Width of the destination rectangle.
u16	outH
	Height of the destination rectangle.
s32	ratioX
	Ratio in X direction of the source rectangle size to the destination rectangle size, encoded as a 32-bit signed fixed-point number. Such a value can be obtained from a floating point number by rsxGetFixedSint32().
s32	ratioY
	Ratio in Y direction of the source rectangle size to the destination rectangle size, encoded as a 32-bit signed fixed-point number. Such a value can be obtained from a floating point number by rsxGetFixedSint32().
u16	inW
	Width of the source rectangle.
u16	inH
	Height of the source rectangle.
u16	pitch
	Pitch size, in bytes, of the source image data (width multiplied by the number of bytes in each pixel).
u8	origin
	How the origin of each pixel is determined. More...
u8	interp
	Sampling for scaled blits. More...
u32	offset
	Image data offset, e.g., a value returned by gcmAddressToOffset() or gcmMapMainMemory().
u16	inX
	X origin of the blit rectangle in the source image. Format is 16-bit fixed point, see rsxGetFixedUint16().
u16	inY
	Y origin of the blit rectangle in the source image. Format is 16-bit fixed point, see rsxGetFixedUint16().
