conversion functions and resource managers. The idea is that the LCL is
widget independent and has no knowledge about the handles. An image handle
will be always the fastest type. That means, that a TBitmap.Handle will be a
gtkpixmap under gtk and a win32 bitmap under win32. This is also true for
TPixmap.

So, I should forget about these things until a widget-independent way of
doing it is thought of?
