2013-03-18[test] Set font sizeBehdad Esfahbod1-0/+1
Previously this test was working because we were not scaling bitmap fonts. We do now, so adjust test.
2013-03-15test: Fix CAIRO_REF_DIRUli Schlachter2-4/+3
Ever since the test output was moved from test/ to test/output/, using CAIRO_REF_DIR to make the test suite succeed no longer works. The test suite was looking for the wrong file names. This patch makes this work again. However, I am not sure that this really is the correct fix. It just seems to work. :-) Reported-by: Darxus <darxus@chaosreigns.com> Signed-off-by: Uli Schlachter <psychon@znc.in>

2013-01-08gl: Do less work when acquiring and releasing devicesMartin Robinson2-0/+183
After acquiring a GL device and the same GL context, surface, and display combination is already active outside of Cairo, do not ask EGL or GLX to change the current context as that may cause a flush on some drivers. Also do not unset the context when releasing the device for the same reason.
2012-12-17test: Add xcb-huge-subimageUli Schlachter3-0/+82
This creates an image surface with a non-natural stride and paints it to a similar surface. In the xcb backend, this causes a call to _cairo_xcb_connection_put_subimage() which tries to send a huge PutImage request. As a result, xcb kills the X11 connection.

Exercise a bug in the determine of clip-bounds when stroking, as reported by ed44. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-10-31pen: First check whether the in/out edges lie within the single pen vertexChris Wilson3-0/+0
In order to prevent underflow when searching for the closing pen vertex, we first need to be sure that it does not simply lie next to the opening pen vertex. As a result we were missing many cases that should have been a bevel (in == out) and generating almost complete round caps instead.

2012-10-16test: Define optional exception classesUli Schlachter3-7/+20
According to musl libc author: "C99 requires the FE_ macros to be defined if and only if the exception they correspond to is supported" So we define these macros to 0 if they are not supported. Support for these FPU exceptions is not necessary for correct functionality, but makes some tests less effective.

2012-06-24test: Exercise bug in joining together spline segments around cuspsChris Wilson3-0/+97
Carl Worth demonstrated a glaring bug in the new stroking code, introduced in commit 545f30856aac98199 (stroke: Convert the outlines into contour and then into a polygon), whereby only a bevel join was being used to connect segments around a sharp inflection point. This adds the two examples he reported to the test suite.
2012-05-31test: Restore bug-seams referenceChris Wilson2-0/+0
An overzealous update after converting antialiasing missed the object of this test was exactly to point out an error due to the antialiasing. So restore it back to the prestine reference and mark the image backend as failing. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2012-05-23test: Increase surface size for get-path-extentsChris Wilson1-1/+1
Whilst generating a glyph run from a string, any glyphs that are far outside the surface (including a substantial guard region) are culled. This affects the path extents. Workaround this by increasing the surface size. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2012-05-14stroke: Don't drop clockwise==0 linesChris Wilson15-0/+0
If the join indicates the pair of edges are parallel, we may be considering the final segment of the spline with a different tangent vector than the slope of the final edge and so lead to false dropping of an edge. This has the effect that the line segments between 'arc arc arc arc' (a rounded rectangle) are no longer horizontal or vertical. As path construction tries to eliminate joins between colinear segments, this optimisation should not be required anyway. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2012-05-11clip: Apply clip boxes to the clip surfaceChris Wilson2-0/+0
As we convert the unaligned clip boxes to a region, we need to process the intersection of the boxes with the clip surface as a separate step. Fixes tighten-box for the base compositor. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

Reducing the number of passes has the usual change in the antialiasing side-effects, as well as the boon of being faster (and theorectically more accurate through reduced loss of dynamic range.)
