A native widgets aren't part of a VCL metafile so they are ignored
when the metafile is replayed. When drawing a dialog to a custom
device, the first draw goes to the metafile, which is then replayed
to the final device, but no native widgets get drawn. This commit
changes this behavior for LOKit where it draws without using the
intermediate VCL metafile.
