The value for

is truncated to the depth of the GC.

Set foreground to pattern of 1's and 0's
Set plane-mask to values larger than the depth.

>>ASSERTION Good A
The
.M plane_mask
specifies which planes of the
destination are to be modified, one bit per plane, with bits being
assigned to planes from the least significant bit of the word
to the most significant bit.
>>STRATEGY
Set foreground to pattern of 1's and 0's
Select a variety of plane masks.
Verify that the expected pixels are drawn.
