[Tuxpaint-devel] Windows & Android (& others?) FontConfig `fonts.conf` parsing

[Bill K. <nb...@so...>]

I've been quite busy lately, and was just trying to remind myself
what's up in the in-progress 0.9.35 version of Tux Paint.

In CHANGES.txt I spotted this entry:

 + WIP Checking for fonts in any locations specified by "<dir>"
   entries found in system-wide and user-level FontConfig config files.
   This allows more fonts, and user-specific fonts, to be found & loaded.
   - TODO - Looks in $FONTCONFIG_PATH/fonts.conf on macOS/iOS,
     `/boot/system/settings/fonts/fonts.conf` on Haiku, otherwise
     the Un*x-specific `/etc/fonts/fonts.conf` and
     `~/.config/fontconfig/fonts.conf`.  Should look in the correct
     places on other platforms.
   - Note: This adds a build dependency on `libxml-2.0`.

Pere and Shin-ichi, I'm sure I asked already, but can you let me know
what else, if anything, we should add so that Tux Paint can find a user's
`fonts.conf` (FontConfig XML configuration file) so the Android & Windows
builds of Tux Paint can also take advantage of this new capability...?

And of course if anyone else out here has suggestions for more OS-specific
paths that we should look at, please speak up!

Thanks in advance!

PS - As a reminder, the _other_ things coming in 0.9.35 (so far) are:

 * "emitter" (heart, stars, sparkles) magic tools
 * text pasting (copy/paste buffer) in Text & Label tools
 * UX improvement to HSV color picker
 * minor doc improvements
 * some build improvements (NetBSD, Slackware)
 * less noise to STDOUT
