Subject: Fix the size of the font returned by wxTextCtrl::GetStyle() in MSW.
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/e170515a9b895080d683dc73b2fdc6299eaae2f6

Fix the size of the font returned by wxTextCtrl::GetStyle() in MSW.

CHARFORMAT stores height in 1/20th of a point, not pixels. Add the correct
conversion to the units used by LOGFONT.

See #13384.
