the WindowType structure. Instead we have a probable relative called bitmapP
of type BitmapPtr. But bitmapP also doesn't have baseAddr in it.

get the base address( bit array) of the bitmap.
> The Emulator gets very angry when I try to move the offscreen bits into
the bitmap using theWindowHandle->bitmapP instaed of
theWindowHandle->gDeviceP->baseAddr and gives memory errors( trying to
access invalid chunk ptr)
