David Robillard 2af9c2180a Push2: Mostly fix scale menu text rendering (#8599)
"Mostly" because there are still some issues with horizontal overlap between
entries, but I think that's something that needs to be addressed separately.

Like earlier issues, this was caused by using a screen-derived or default
cairo/pango context.  I also tinkered with some constants to make things look
sensible to me, and hopefully everywhere since it should always look the same
with the context fix.
