> Moving away from DirectWrite sounds like going -horribly- backwards...
Sorry, I was not suggesting we could abandon DirectWrite. I was suggesting that
until we can improve our DirectWrite implementation--and ideally restore a GDI+
rendering--that the default rendering on Windows build should not be OpenGL
when a user's hardware supports it.
IIUC at 5.3.0 with Default rendering on Windows, we've reverted to "legacy"
GDI. The DirectWrite based GDI+ that was providing better sub-pixel rendering
had to be dropped as our GDI+ implementation was not behaving well with
HarfBuzz. Likewise misbehaving with HarfBuzz our OpenGL rendering remains
DirectWrite dependent--but that can not be changed.
So the choice for users who have OpenGL capable hardware is between a less than
perfect script layout with OpenGL rendering enabled, or a somewhat reduced font
rendering quality with "default" rendering now missing better DirectWrite GDI+
sub-pixel rendering.
What rendering should Windows configuration enable by default--Default or
OpenGL?
Suspect at 5.3.0 we will be hearing quickly from users _without_ OpenGL capable
hardware about losses in their text quality. Can't be avoided, and can't be
corrected until we can improve our DirectWrite implementation.
