Allow passing flags to glyph.importOutlines()

[Khaled Hosny-2]

I'm using FontForge to import a large set of MetaPost generated PS files
into font, using python scripting is handy but it lacks "Handle Erasers"
feature available in the GUI, which I need.

The attached patch allows passing optional flags to
glyph.importOutlines(), the flags are only passed to PS importing
function as it doesn't make sense for other image formats.

Regards,
 Khaled

Subject: [PATCH] Allow passing flags to glyph.importOutlines()

The flags are passed to SVImportPS only, it does't make any sense to
other image types.
