How does one go about finding the active BitMap?  The method I am using now is:

move.l  GraphicsLibrary,a6    ;link to Graphics Library
move.l  34(a6),a1             ;Pointer to View
move.l  (a1),a1               ;Pointer to ViewPort
move.l  36(a1),a1             ;Pointer to RasInfo
move.l  4(a1),BitMapPointer   ;Pointer to Bitmap

It finds the active BitMap only if there is one screen open, otherwise it
tends to find the wrong BitMap.  I have a feeling that somewhere along the line
there is a list of screens I have to search through somewhere.  Is there any
easy way to find just the BitMap of the ACTIVE screen?
