render document thumbnail directly to bitmap, without metafile
I don't see the point of taking the detour via GDIMetaFile and
then immediately drawing using it to a bitmap. Simply draw directly
to a bitmap. Especially given that when drawing to a metafile
some fast cases are skipped, e.g. DrawTransformedBitmapEx()
avoids DrawTransformBitmapExDirect() and resorts to using the slow
BitmapEx::getTransformed(). E.g. with tdf#136223. this makes
SfxPickListImpl::AddDocumentToPickList() go from 30% to 13%
of the total document loading time.
