Title: Reverse premultiplied alpha transform before saving bitmap data from SWF to PNG

SWF seems to store premultiplied RGBA bitmap data while PNG requires non-premultiplied input.
Absence of this conversion causes extremely dark shadows on semitransparent areas.

Also another small fix skips unsupported objects in SWF without crashing whole conversion process.
