Ask questionshintfull setting is not respected

I've configured hintfull in fontconfig:

<?xml version='1.0'?>
<!DOCTYPE fontconfig SYSTEM 'fonts.dtd'>
<fontconfig>
 <match target="font">
  <edit mode="assign" name="hintstyle">
   <const>hintfull</const>
  </edit>
 </match>
</fontconfig>

This is recognized by alacritty. I've not disabled antialiasing for any font. Therefore alacritty uses the following code path:

https://github.com/alacritty/alacritty/blob/fde2424b398dadd2310686b365041189decd1d63/font/src/ft/mod.rs#L491

hintfull is not applied in this case.

Disabling antialiasing via fontconfig makes the font ragged in alacritty and other programs and is therefore not an option.

This problem is specific to alacritty. Hinting works as expected in all other programs I'm using.

The following patch fixes the problem:

For full, it uses FT_LOAD_TARGET_DEFAULT, unless rgba has been enabled, in which case it uses one of the FT_LOAD_TARGET_LCD modes. This matches Alacritty, I think?

This is how urxvt renders the same font. It seems much closer to the patched alacritty version than the unpatched one.

useful!
