don't copy not needed bitmap
The problem here was that we copied 37.059 times the complete hugh bitmap
(37.059 isolated transparency groups !!!) and then never used it because the
transparency groups were isolated :-)
BTW, there is enough room for performance increasements even for non isolated
transparency groups:
1. The complete bitmap is copied but only the alpha channel is used and
2. even from the alpha channel only a part is needed!
(s. splash->setInNonIsolatedGroup())</pre>
