Subject: Small bugfix for makeglyphfontspecs call in drawregion
X-Git-Url: https://git.danieliu.xyz/?a=commitdiff_plain;h=89cf0fc597a2bcc16b1516c6f6d750a06175f1c7;p=st.git

Small bugfix for makeglyphfontspecs call in drawregion

Here's a patch that fixes a bug when calling `makedrawglyphfontspecs'
in `drawregion'. Wasn't offseting the pointer into the input glyphs
array by `x1'. The bug isn't causing any problems currently, because
`drawregion' is always called with `x1' and `y1' values of 0, but if
this ever changes in the future, the bug would certainly cause some
problems.
