It works nice.
Well, just after your new lines there is another hack with aliasing for
http://openoffice.org/bugzilla/show_bug.cgi?id=99665 . It solves the
problem where the aliasing caused problems => we should be more careful
with setting aliasing to ANTIALIASING_ENABLE_B2DDRAW globally.
I prefer the more conservative approach from i#99665. It modifies the
current aliasing using "byte or" (operator |) and restores the original
aliasing at the end of the "if" block.
I see that the aliasing value is always modified by byte operators '&',
'|'. Try to search for ANTIALIASING_ENABLE_B2DDRAW at
http://opengrok.libreoffice.org/
So, what do you think about the attached patch?
It uses the conservative approach from i#99665 also for your two
changes. Also it combines your fix with the fix for i#99665 to avoid two
nFormerAntialiasingAtOutput variables.
I would prefer to sort this out before we cherry-pick it to
libreoffice-3-4 branch.
Best Regards,
Petr
