The purpose of this call is to draw a path and write the output as a path in the block.
If thickness is zero, fill bits 3, 2 must not be 01.
If thickness is non-zero, fill bits 2-5 must not be 0110. i.e. Filling just the boundary pixels.
Draw_Stroke is similar to this call, however, it outputs the the screen rather than to a block.
