|

The side vertex is at (vx,vy)
|

The opposite side goes from (xr,yt) to (xr,yb)

VGI Vertical Striped Rectangle (9)
|
||||
|
||||
VSTRP c1 c2 x1 y1 x2 y2
|
||||
|
||||
Draws a rectangle, but this time the two colors are raw bitmaps
|
||||
for the output colors, but to use even/odd columns.
|
||||
On apple II this allows repeating pattern, but since it's a multiple
|
||||
of 7 you can't get true stripes (for that we'd need a 4-byte
|
||||
repeating pattern)
