That commit made the ChangeLog regenration rule to depend on .git/HEAD,
not .git/. However, the contents and timestamp of that file does not
change when you commit something locally. Hence, ChangeLog could remain
stale. Depending on .git/ does the job.
Validate that we find an appropriate depth for the Xlib surface, before
attempting to create the surface. This was manifesting itself with
XInitImage() failures during _draw_image_surface() (actually detected as
a segmentation fault in XPutPixel() due to an incomplete XImage). So we
also add a couple of asserts to ensure that XInitImage() is successful -
which to the best of our knowledge, they should always be.
If the internal buffer is wrapped in an image surface in acquire_dest_image,
that image surface needs the current clip region propagated to it. If not,
then the clip needs to be applied at release_dest_image time.
Using glyph indices with Type 1 fonts on a printer DC does not work.
Previously there was a temporary fix where Type 1 fonts were printed
as filled paths.
Now that _cairo_scaled_font_subsets_map_glyph() provides the reverse
mapping of the glyph index fix this by converting the glyph indices
back to the unicode values when printing Type 1 fonts.
Prevously all show_text_glyphs() clusters were using ActualText. This
fixes that.
I have a feeling that the following scenario is broken still though:
- show_text_glyphs maps glyph 1 to some utf8 text different from
what index_to_ucs4 will give for glyph 1. This will assign the
utf8 text to glyph 1's ToUnicode.
- show_glyphs shows glyph 1. Since cluster has no utf8 text, we
won't use ActualText and fall back to ToUnicode. But the ToUnicode
value assigned to glyph 1 is non-standard now. We should use
ActualText.
I have not verified this hypothesis though.
And update user-font text_to_glyphs() method to match.
Currently disable the win32-font text_to_glyphs(), until that one
is updated. Or better yet, remove it and implement ucs4_to_index().
It's the toy font API afterall.
The init func does not actually need to draw anything, but having a cairo_t
similar to that passed to render_glyph is handy for computing font extents.
This is because cairo makes doing some things really hard (if not impossible)
without a cairo_t.
The user-font-proxy test case is a great example of how the added cairo_t
makes life much easier.
