Hi, Dmitry Timoshkov!

Needs to reselect font again after restore old_mode in case
pExtTextOutW-> iGraphicsMode != old_mode. Otherwise, the font will
remain with the wrong glyph orientation.
I can write a test demonstrating the problem.

Resect font is needed only if pExtTextOutW-> iGraphicsMode is
GM_COMPATIBLE. This is performance optimization for GM_ADVANCED.

Thank, you!
