// Due to the resource problems in Win95/98 with bitmap resources I
// will change this handle bitmap providing class. Old version was splitting
// and preparing all small handle bitmaps in device bitmap format, now this will
// be done on the fly. Thus, there is only the one big bitmap remembered. With
// three source bitmaps, this will be 3 system bitmap resources instead of hundreds.
// The price for that needs to be evaluated. Maybe we will need another change here
// if this is too expensive.
