* Issue #1274 - Part 1: Adopt the cairo version as our own.wolfbeast2019-11-07-31460/+650
| | | | | | | | | - Move header licensing from tri-license to MPL 2.0. MPL-compatible other licensing has been retained where originally present. - Remove individual superseded licensing terms. - Remove patches, outdated readmes & incomplete patch summaries. - Remove incomplete cairo release notes (only went up to 1.6.4 anyway). - Rewrite COPYING to indicate the current state of the library in tree.
* Correctly return zero vertices if clipping plane 0 or 2 clip away theMarkus Stange2019-09-04-15/+91
| | | | | | | | | | | | | | | | | | entire polygon. This fixes a bug that was introduced three years ago in BZ bug 1268854. What happened was that the final pass over the polygon assumed that the current polygon was living in plane[0]. But due to the double buffering, the "current" polygon alternates between plane[0] and plane[1]. The bug had also introduced an early exit so that we could hit the final pass at a time where the current, now empty, polygon was in plane[1]. So we would incorrectly treat all 32 points in plane[0] as part of the final polygon. This bug was responsible for intermittently unreasonable numbers in CompositorOGL's fill rate / overdraw overlay. This fixes a regression caused by the fix for CVE-2016-5252.

* Enable double buffering when using XRENDER.Mihai Moldovan2019-05-22-1/+14
| | | | | | | | | This fixes flickering/bars/stripes showing up during quickly-updating operations on Intel hardware when using XRENDER. For more information, refer to the code comment. See #1061
* When using XRENDER, create Xlib-based offscreen image surfaces.Mihai Moldovan2019-04-27-8/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mozilla tried to enable XRENDER support with backends other than Cairo in 286348:e13aaaaf1962 / https://hg.mozilla.org/mozilla-central/rev/e13aaaaf1962 - at least until they decided to completely remove XRENDER support. The change looked innocent enough, but actually turned out to do exactly the opposite: it forcefully enabled image offscreen surfaces with GTK2 when it was previously disabled (since gfxPrefs::UseImageOffscreenSurfaces() will always return true) and, by extension, disabled the XRENDER-based functionality by creating a non-Xlib surface. Interestingly, a previously enabled double buffering check was also disabled by this, but since the comment for this was diverging with the code, that behavior just sounds like yet another bug. Instead of disabling image offscreen surfaces (at least when using the GTK2 backend), let's force the creation of Xlib-based image surfaces when XRENDER support is enabled. This will let UXP use the more common/modern code paths, but also make scrolling much faster again. Too fast scrolling may induce tearing (if not smoothed), but on the other hand performs much better in remote computing contexts. As an added benefit, GTK3-based builds should roughly behave the same way. Further tests with the GTK3-backend enabled will be required in the future.

* Remove texture layout endian-ness check for Moz2D.wolfbeast2019-03-05-10/+0
| | | | | | | | This resolves #986. This removes endian-based inversion of texture layout aliases when represented as uint32. This inversion was incorrect and would cause unknown texture formats as a result on big-endian machines (PPC64).
* Don't trust convexity when applying transforms.wolfbeast2019-02-18-1/+1
| | | | | | | | | | | | In theory, a convex shape transformed by an affine matrix should still be convex. However, due to numerical imprecision of floats, when we try to determine if something is convex, we can get different answers pre and post a transformation (think of two line segments nearly co-linear). Convex paths take a faster scan converter, but it is only well behaved if the path is, in fact, convex. Thus we have to be conservative about which paths we mark as convex, and cant's trust transformed paths to retain their convexity. We re-calculate when a transform is applied.

* Switch to Lanczos scaling from Hamming to get acceptable fast downscaling.wolfbeast2018-07-14-15/+10
| | | | | | | | | | In visual tests we see that Hamming-1 is not as good as Lanczos-2, however it is about 40% faster, and Lanczos-2 itself is about 30% faster than Lanczos-3. The use of Hamming-1 has been deemed an unacceptable trade-off between quality and speed due to the limited pixel space it operates in, so we pick Lanczos-2 here. On modern hardware, Lanczos-2 doesn't have any noticeable impact in normal use.
