I need to resolve the font face name (for example, "Arial") as returned by wxPython, to the Windows filename (for example, c:\windows\fonts\arial.ttf) as required by the Image module, and it looks like GetFontData() from the Windows API is the solution.

Although it IS possible to find this information using the API, it is
quite tedious.  You'd need to have a DC, create an HFONT, select it into
the DC, then run GetOutlineTextMetrics, which is not a Python-friendly
API.  You get back a long structure where some members include the
offset to the strings you need.

A much better solution is to search through the registry values in
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts.  That maps each
font name to its corresponding file name.
