Matthias Clasen ce09db1401 Bump pango req to 1.49.1
We are using pango api that was introduced in 1.49.1
without ifdefs, so we should require it.
2021-09-04 09:41:20 -04:00
Matthias Clasen ed96414483 Avoid hand-rolled color glyph information
Followup to b244f31337. Pango provides color glyph
information for us now, so we don't need to steal a
bit anymore.
2021-09-04 09:39:29 -04:00
Matthias Clasen e6de8a1746 Fix text node diffing
Now that text nodes carry flags, we need to compare
them (even though it is very unlikely that they will
differ from node to node).
2021-09-04 09:37:29 -04:00
Matthias Clasen db1fc454ee Redo font options handling
Avoid cairo types in the API by introducing a
GskTextRenderFlags enum.
