If a drawing is rendered and needs to be duplicated along the X-axis or Y-axis, then a single
write to the 2DGC_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.
Polygon fill supports filling of complex (convex and concave) polygons. The number of vertices
in the polygon is limited to 16 and is programmed into 2DGC_VXRs and 2DGC_VYRs registers.
In order to obtain a specific complex polygon, vertex registers (2DGC_VXRs and 2DGC_VYRs)
must be written in a specific order: vertex registers following the first one define adjacent verti-
