This code is never used because outline glyphs that go through the
fallback path are always embedded with Type 1 fallback. The only fonts
that are embedded as Type 3 are bitmap fonts.
The PDF emit path orginally had two matrix transforms in the path
struct. One for strokes and one for fill/clip. As only one transform
at a time is ever used this can be simplified.
The deflate stream has bounded (constant) memory overhead, whereas
compress_dup() allocates memory proportional to the uncompressed data.
This replaces compress_dup() usage with a compressed PDF stream for
emitting images, alpha masks and font subsets, and eliminates the
compress_dup() function.
Previously we were passing the root window of the same screen.
Letting the X server know the actual Drawable for which we're
trying to be similar allows the X server to be more efficient.
cairo_has_current_point() can be used to determine whether a current
point is defined. We introduce this new symbol with a boolean return
value to avoid the versioning ambiguity of modifying
cairo_get_current_point(). This way we also don't have to map what
should be a routine operation to an error condition as was previously
proposed.
Make sure that we don't test lines that start or end inside the box,
since our algorithm will find intersections on the wrong ends on the
line, and not count them.
The PS Language Reference requires the PS miter to be >= 1.
The PDF Reference does not specify miter limits however acroread fails
to display pages when the miter is < 1. Older versions of ghostscript
crash when the PDF miter is < 1.
The image/meta-pattern is written once. A PS pattern twice the size of
the cairo pattern is created and the surface drawn four times in a
reflect pattern inside the PS pattern.
This fixes the extend-reflect and extend-reflect-similar PS test
failures.
Store the surface size in each pattern and smask group and use this
size when the pattern/group is emitted. This is required as a pattern
or group may be used from a meta surface with a different size to the
PDF surface. However the pattern or group is emitted after the the meta
surface content has been emitted and the surface size has been
restored to the the page size.
This fixes the following pdf test failures:
extend-reflect-similar
extend-repeat-similar
mask
This seems redundant with the recent testing of all test cases
against similar surfaces. Plus, it hasn't had a reference image
anyway which was causing problems with the recent extra checks
for missing reference images.
