[PATCH v2 6/6] gdi32: Reselect font and pen when changing world transforms for enhanced metafiles.

Mon Apr 19 02:29:10 CDT 2021
Reselect font and pen into enhanced metafile device contexts after world transform is changed so
that content can be drawn using the correct size. Also modifying the world transform for enhanced
metafiles doesn't generate EMR_SELECTOBJECT records according to winedump outputs.
Fix an issue that Tally may produce a print preview with a too large font or with a black side bar.
