[cairo] Re: Drawing text with Windows bitmap fonts

[Jan Slupski]

Another issue that got stucked with open question:

(...ignore WIN32_FONT_LOGICAL_SCALE disussion in between...)
http://lists.freedesktop.org/archives/cairo/2007-January/009293.html

In short: there are Windows that fonts that are picked up by engine
but are not TrueType. Later on win32 font handling functions fail
because they are not-appropriate for non-TrueType fonts.
In effect text labels are not shown at all.


Myself I'm using following workaround to guarantee that win32 logic
picks only TrueType fonts:
