by reverting essential parts of "Font rotation at arbitrary angles"
which was once committed in several steps:
Initial commit (PR#1207)
0.4.12-dev-243-g
f757a13519
broke font rendering for GTK apps CORE-15623
Second commit (PR#1238)
0.4.12-dev-558-g
64987cf273
restored font rendering in GTK apps but introduced slowdown CORE-16020
Katayama agreed to the temporal revert and will try to come up later
with a performance optimized version.
We revert in 0.4.12-RC and 0.4.13-dev.
The revert will cause failure-increases in gdi32:TextTransform
