/** Little wrapper encapsulating an XBitmap
|
|
|
|
This is to insulate us from changes to the preferred
|
|
transport format for bitmaps (using a sole XBitmap here is
|
|
a hack, since it is not guaranteed to work, or to work
|
|
without data loss, across different canvases). And since
|
|
we don't want to revert to a VCL Bitmap here, have to wait
|
|
until basegfx bitmap tooling is ready.

TODO(F2): Add support for Canvas-independent bitmaps
|
|
here. Then, Slide::getInitialSlideBitmap and
|
|
Slide::getFinalSlideBitmap must also be adapted (they no
|
|
longer need a Canvas ptr, which is actually a hack now).
