13a5624277 Rename cairo_image_surface_stride_for_width to cairo_format_stride_for_width 
Thanks for Behdad for the suggested name improvement. Also, make
it more clear that the stride passed to cairo_image_surface_create_for_data
should come from calling cairo_format_stride_for_width with the
same width.

dc67de3d8b Add cairo_image_surface_stride_for_width 
Document this function as a required call to get the correct
stride value before calling cairo_image_surface_create_for_data.
This means that previously-failing calls with non-multiple-of-4
stride values are now documented as errors. Also, we now have
the possibility of moving to more stringent alignment constraints,
(one can imagine doing 64-bit or 128-bit boundaries for example).

bae496df11 [test/bitmap-font] Test under all combinations of hinting, test font metrics too 
This is now failing as we compute NAN font metrics for bitmap-only fonts under
disabled metrics hinting.  A very infamous bug excercised with PangoCairo's PDF
output.

c480eedbb5 Test and document extents of degenerate "dots" 
It's a common idiom to stroke degenerate sub-paths made with
cairo_move_to(x,y);cairo_rel_line_to(0,0) to draw dots. Test
that we get the desired extents from cairo_fill_extents,
cairo_stroke_extents, and cairo_path_extents for these cases.

Also document that the cairo_path_extents result is equivalent
to the limit of stroking with CAIRO_LINE_CAP_ROUND, (so that
these "dot" points are included), as the line width
approaches 0.0 .

a zero-area rectangle, but with a non-zero offset.

4177208be6 [cairo] Add cairo_path_extents() 
This new function gets the extents of the current path, whether
or not they would be inked by a 'fill'. It differs from
cairo_fill_extents() when the area enclosed by the path is 0.

Includes documentation and updated test.

81e029edda Add new miter-precision test. Checks miter joins at many scales. 
This demonstrates an error in cairo where miter joins are replaced with
bevels at high scale factors due to a test added to eliminate wild miters
drawn when the line faces are nearly parallel.

3bf06c3366 [test/*] Create new surfaces using the group target. 
cairo_get_target() returns the original surface passed to
cairo_create(), and not the current destination as required when
testing drawing to the same surface using multiple contexts.

For completeness we also use the group target when creating similar
surfaces within the tests (to check that similar surfaces of similar
surfaces also work).

281b11aef1 [cairo-test] Use CAIRO_OPERATOR_SOURCE when painting the group surface. 
To correctly copy a surface onto the destination irrespective of its

uninitialized pixels to be mixed into the result and the failure of
many tests for the similar surface. Oops...

b81c8473bd [test] add test for gradient with no stops 
Boris Zbarsky reported a bug where having zero stops in a
gradient pattern would crash in the quartz surface. This
test checks for that case. Mozilla bug#407104.

This also crashes testing pdf; and the ps, svg surfaces
look suspicious (they reference stops[0]) but I havent
been able to test them yet.
