2015-06-18pattern: allow for a floating one pixel rounded difference.Alban Browaeys1-5/+5
That is if the difference between the origin and the end is bigger than .5 round up regardless of the coordinates. Round the difference of the floats instead of rounding the floats then diff them.

2015-06-18cairo-script: Rename struct member to avoid name collision on AIXBryce Harrington2-38/+38
On AIX, the token jmpbuf is a pre-processor macro. cairo-script-scanner.c includes a private struct with a member named jmpbuf which gets renamed to __jmpbuf when AIX's sys/context.h has been included. While judicious ordering of includes might kludge around this problem (by causing all references to .jmpbuf to become .__jmpbuf), it's better to simply select a new name for the struct member that won't suffer the collision.

2015-06-04polygon-intersection: Try not to invoke undefined behaviourMassimo Valentini1-2/+2
Optimizing compilers aggressively remove code that is executed only after an undefined behaviour occurred. Also, the difference of two (non char) pointers hides an integer division that, because the divisor is known at compile time, is transformed into a multiplication by a pseudo-reciprocal, and in this case the difference is not always a multiple of the divisor, resulting in an invalid comparison predicate.

2015-06-04polygon-intersection: Include approximation in intersection pointsMassimo Valentini1-72/+67
In Hobby's paper it is proved that INTERSECTION events can be processed in any order by ignoring intersections between edges non-adjacent in the active edges list. But with respect to START/STOP events they must be processed in order. Because START/STOP events have always exact y, it is sufficient to know whether an integer y intersection is a default/excess approximation of the exact to properly sort events.

2015-06-04Support new-style __atomic_* primitivesNathan Froyd2-0/+102
Recent versions of GCC/clang feature a new set of compiler intrinsics for performing atomic operations, motivated by the operations needed to support the C++11 memory model. These intrinsics are more flexible than the old __sync_* intrinstics and offer efficient support for atomic load and store operations. Having the load appear atomic to the compiler is particular important for tools like ThreadSanitizer so they don't report false positives on memory operations that we intend to be atomic.

2015-04-21[ft] Return CAIRO_STATUS_FILE_NOT_FOUND if font file can't be openedBehdad Esfahbod1-15/+35
A common source of error when people are setting up pango on a new device is when font files don't have the right permissions and cannot be opened. Cairo was returning out-of-memory before, making the Pango error message useless. With this change, cairo will return file-not-found, and pango prints that out. It's still not ideal; a ENOACCESS equivalent would have been better.
2015-04-20Avoid appending an empty slot to an user data array when user_data is NULL.江頭幸路1-0/+3
Otherwise, calling cairo_set_user_data(cr, key, 0, 0) many times causes a long user data array, almost all of whose slots are empty. It leads to unnecessarily much memory consumption and long execution time of cairo_set_user_data(cr, key, 0, 0) and cairo_get_user_data(cr, key) after it.

2015-04-08test: Fix coverage-intersecting-triangles referenceAndrea Canciani3-1/+1
Commit 4e3ef57bc892b0b046c486390adc7164a1de64de added coverage-intersecting-triangles with an incorrect reference and generator. The test checks the rasterization of two overlapping triangles in the following position: . . |\ /| | X | |/ \| .---. Since the triangles have both vertical and horizontal sides of size x/WIDTH, the expected coverage is 3/4 (75%) of (x/WIDTH)^2. The original code, instead, was checking for a coverage of 0.75*x/WIDTH, as if one of the sides was always 1 unit long. The image and xlib backends still suffer from some jitter, caused by the approximation of the actual coverage by means of sampling. For this reason their references are still considered XFAIL, even though their result now looks mostly consistent with the expected reference.

2015-03-13Harden make-cairo-test-constructors.shAndrea Canciani2-2/+4
The make-cairo-test-constructors.sh script executes several commands without checking their success. This can lead to undetected errors, like those fixed in 86fad78fcd2bf987249890aea4eabcce02a58f45. The script now exits with an error status if no file is input. Moreover, it sets the '-e' flag, so that if a command fails, the whole script is immediately terminated with an error. In the Makefile.am, the script result is now checked and the target file is removed upon error. This ensures that the 'cairo-test-constructors.c' target completes succesfully only if no error occurred. Reviewed-by: Bryce Harrington <bryce@osg.samsung.com>

Since 70cc8f250b5669e757b4f044571ba0f71e3dea9e the quartz backend is using some APIs that are not available on MacOSX 10.4 directly (i.e. without detecting their availability through dynamic linking).
