GtkSourceMap should incorporate Builder's font modifications
Builder uses a custom font for its GtkSourceMap which is nice and compact, and would make a better default than the current Monospace 1
. I can't actually test, but I'm assuming that this also makes the GtkSourceMap rendering faster due to the simplicity of the glyphs.
Personally, I also want this because I'm trying to play with using GtkSourceMap in Meld and the introspection bindings don't have what I need to reproduce the font map modifications that Builder does.
