Make hexbox usable as an attribute
Submitted by Behdad Esfahbod
Link to original bug (#503083)
Description
The hexbox code is quite complex because of hinting issues, etc. It would be a useful feature to have shape-like attributes that will render a box with text inside. Can be used to show tabs, newlines, ... more usefully for example. For newlines maybe we should do that by default (bug 501482).
Anyway, something like:
pango_attribute_box_new (const char *text);
text should be ASCII, and rows/cols are automatically determined.
(and Behnam can finally get his "ZWNJ" box)
