The plot thickens.
>From Palm_OS_Reference:
If the bitmap has multiple depths (is a bitmap family), the closest
match less than or equal to the current draw window depth is used.
If such a bitmap does not exist, the bitmap with the closest match
greater than the draw window depth is used.
So I deleted the 1-bit bitmap from the family, so that only the 2 bit bitmap
exists. Nothing is drawn.
On a IIIc, it draws the 2 bit bitmap just fine.
What am I missing? Is there a call I need to make that says "Turn on Gray
Scale drawing on a 3.5 gray scale device"?
