44.3.1.8 Relative Block Transfer
A block of data is copied (or xor/or/and/xnor/nand/not/nor/xnor) from the start position loaded into start x and start
y registers to a position offset based on the target position loaded into target x and target y registers with respect to
start position. The size of data is based on size x and size y registers.

44.3.1.9 Block Transfer with Update X/Y
If a drawing is rendered and needs to be duplicated along the X-axis or Y-axis, then a single write to the
TDGC_GOC will duplicate the drawing in the desired direction. This saves writing actions to startx, starty, endx,
endy, color and logic operation registers and results in a faster rendering.
