Subject: Only word wrap on spaces
X-Git-Tag: 0.9.12~17
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a3d0b507bd1bb18067de7b948f5371197dc142b9;p=libass

Only word wrap on spaces

It looks like VSFilter only ever wraps on spaces, even if the line
length is going to overflow. We should do that as well.
Fixes a pretty confusing problem with scrolling vertical text.
