Subject: gdi32/tests: GetTextExtentPoint should give repeatable results

These are tests for bug 32529. Since commit ebaf5ea17623268fb1c0f68b1cf9a5984bd4e46e
(Don't load bitmap glyphs when using subpixel rendering in GetGlyphOutline)
GetTextExtentPoint returns different results before and after glyphs are loaded,
at least for wine's Tahoma.
