2013-04-04boilerplate/gl: Disable thread awarenessMartin Robinson2-0/+5
This dramatically speeds up testing on NVidia and actually makes it possible to run traces within a reasonable amount of time. cairo-perf-trace results for: NVIDIA Corporation GeForce GTS 250/PCIe/SSE2 3.3.0 NVIDIA 310.14 Before: test min(s) median(s) stddev. count gvim 30.924 31.251 0.72% 5/6 firefox-fishbowl 168.751 201.017 12.46% 8/8 (exited early) After: test min(s) median(s) stddev. count gvim 1.294 1.325 1.79% 6/6 firefox-fishbowl 18.540 19.104 1.54% 6/6
2013-04-04boilerplate: Add a mode for running threaded perf testsMartin Robinson1-1/+6
This is useful because the GL backend runs much faster on some drivers when thread awareness is disabled.
2013-04-02win32: fix corrupted drawingMarc-André Lureau1-1/+2
Fix src bitmap coordinates, which origin is bottom-left. This is apparently a bug in StretchDIBits(), according to some comments on MSDN API documentation. The backend used to have this coordinate change in the past: if (!StretchDIBits (dst->dc, /* dst x,y,w,h */ dst_r.x, dst_r.y + dst_r.height - 1, dst_r.width, - (int) dst_r.height, /* src x,y,w,h */ src_r.x, src_extents.height - src_r.y + 1, src_r.width, - (int) src_r.height, src_image->data, &bi, DIB_RGB_COLORS, SRCCOPY)) https://bugs.freedesktop.org/show_bug.cgi?id=61876

2013-03-22boilerplate: rename xcb-render-0.0 to xcb-render-0_0Uli Schlachter1-2/+2
The test suite uses dots to separate the backend name from the content type. Thus, the backend name must not contain any dots. The xlib backend already calls its RENDER 0.0 target xlib-render-0_0 for this reason. This commit makes the xcb backend match this.

2013-03-22test: Fix handling of dots in CAIRO_TEST_TARGETUli Schlachter1-0/+2
Before this, the following happened: $ CAIRO_TEST_TARGET=image,xcb-render-0.0 make test Cannot find target 'image'. Known targets: image, [...] The reason for this is that _cairo_boilerplate_target_matches_name() doesn't get a null-terminated string, but instead has a pointer to the end of the string. However, strpbrk() expects a null-terminated argument and thus could return a result which points past the end of the input. This commit fixes exactly this.

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.
2013-03-18gitignore: negate gitignore for static pkgconfig filesMatt Sealey1-0/+4
Commit 781f253 adds a rule cairo-*.*.* to .gitignore in the root dir. Unfortunately this matches several src/cairo-*.pc.in files in the src directory. The build system requires these files to be present, but the rule is allowing them to be ignored. For example, when extracting a cgit snapshot tarball and checking it into another git repository, these files get left behind. Any accidental changes to these files will go unnoticed by a 'git status' (possibly creating bad installs) and any intentional changes could not be committed (git commit -a will miss them, and every one will need to be forced). This is not really desirable. We don't want to unignore *.pc.in here since there are many, many autogenerated files with this name, and the cairo-*.*.* rule is in general quite useful and doesn't warrant modification (although it could be made a little more specific), so we just make these 4 files a special case and negate the match with full filenames in src/.

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>

2013-03-15mempool: Reduce an assert into an error return for get_buddy()Chris Wilson1-1/+2
If we ask for a buddy that is outside of our allocation that is an error that should not happen with a power-of-two allocated zone... However, since it has been seen in the wild, we can safely return that there is no buddy rather than die in a too-late assert.

2013-03-14stroke: Use round-joins near inflection points of splinesMartin Robinson1-0/+36
Similar to b7bd5ae4f3da44131261711bb236cd7aa24a3ae3, but applied to the fallback stroke shaper.
2013-03-14stroke: Fix large line widths for fallback stroke shaperMartin Robinson2-8/+116
Fix the test case line-width-tolerance for the fallback stroke shaper. Instead of drawing quads between spline points, draw triangle based on the actual spline edges. This roughly follows the approach of the tristrip and polygonal shapers.
2013-03-14path: Fix a bug in line intersectionMartin Robinson1-12/+27
Before the intersection code was not taking into account that both quotients are required to be in the range (0,1) for the segments to intersect or handling the case of negative numerators and denominators.
2013-03-08gl: Setup operands when the vertex size changesMartin Robinson1-12/+17
Previously _cairo_gl_composite_setup_vbo was overwriting the old context vertex_size, while _cairo_gl_context_setup_operand was relying on it to determine if the vertex size changed. Instead of a fragile ordering of statements, pass whether the vertex size changed as an argument to enforce the calling order via method parameters.

2013-03-08[FT] Prefer downscaling bitmap glyphs to upscalingBehdad Esfahbod1-3/+12
Say, you have bitmap strikes for sizes 50ppem and 100ppem. To render at 60ppem, it's much better to downscale the 100ppem bitmap than upscale 50ppem one. Prefer downscaling.

2013-02-19image: Compare against the true size of the embedded bufferChris Wilson1-1/+1
When querying whether the run is small enough to fit inside the pre-allocated temporary buffer, we need to avoid comparing against sizeof(buf) as buf is a variable length array and so sizeof() is meaningless.

2013-02-15win32: Free the fallback upon finishChris Wilson1-0/+3

2013-02-08xlib: Only apply the dst offset to the glyph strings onceChris Wilson1-6/+6
The elts offset is a delta from the previous glyph coordinate. So by subtracting the dst origin everytime, we were accumulating a glyph position error. Instead we just want to offset the starting coordinate and then always use relative positions. Reported-by: Theo Veenker <T.J.G.Veenker@uu.nl> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-02-08polygon: Avoid computing the unused intersection coordinatesChris Wilson1-5/+8
If we only ignore the result of the computed boundary intersection, because the edge is inside that boundary, then we can simply forgo the calculation. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2013-02-08polygon: Only rely on the computed boundary intersections for crossing edgesChris Wilson1-10/+25
If we need to extrapolate the edge to the boundary, then we run the risk of an overflow for an immaterial result. So if the edge does not cross the boundary, we can simply use the corresponding end-point and not emit the boundary segment.

2013-02-05type1-subset: in latin subsets replace glyph names with standard namesAdrian Johnson1-2/+17
When using WinAnsiEncoding in PDF the glyphs are keyed by glyph name. We need to ensure the correct names are used and can't assume the glyph names in the font are correct. Bug 60248
2013-02-04gl: do not force flush everytime uploading a glyph image to glyph cacheHenry Song6-15/+24
In normal cases, we want to flush pending operations reading from the texture before modifying its contents. However during uploading of glyphs into the glyph cache, we repeatedly modify the texture as we construct the vbo (whilst referencing it for that operation). We track unused areas in the glyph cache so that if we run out of space, we can explicitly flush the pending glyphs and start afresh and avoid having to flush the operation in common case.
