Subject: Disable caching of rotated glyphs.
X-Git-Tag: 0.9.7~310
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=bfc6644b94de185dddd0eaf23ac5d6893438901a;p=libass

Disable caching of rotated glyphs.

The following commits will add perspective distortion to the glyphs rotated
with \frx and \fry. Somewhere along the way correct caching of such glyphs
will become impossible, but in the end everything will be fine.
