First, check the return value of winScreenMode to make sure you are in gray mode. If
not, then the OS is correctly mapping your 4-bit
bitmap to 2-bit.
But, I believe the naming convention you described below is obsolete.
The way it's done now (correct me Heather) is to create a bitmap family and then
populate it with bitmaps of different depths. The OS
then picks the bitmap that matches the current graphics mode to display.
If you have a version of Contructor that doesn't support bitmap families, than it is
likely designed for pre-OS3.3, which meant that
4-bit wasn't supported.
