* Reduce double-copying of textures when flipping upside downRhys Weatherley2009-12-021-7/+15
| | | | | | | | | | | bindTexture() flipped images in-place, to reduce data copying. But there is one case where the in-place is worse: when the QImage is not detached. In that case, the flip was copying the entire image and then flipping the lines, effectively processing the contents twice. The new version uses mirrored() to reduce the overhead for non-detached images. Reviewed-by: Samuel
* Added caching of vectorpaths to the GL paint engine.Gunnar Sletta2009-12-013-5/+116
| | | | | | | | | | | | | | | The first time a path is drawn we call makeCachable on the path, which means that if it is drawn again, we start caching it. This is a bit of a trick to avoid caching paths that are drawn once and discared while at the same time cache paths that are reused automatically. The GL engine owns the vertex information and is responsible for cleaning it up. If the vectorpath is destroyed first, it will call the cleanup function. if the engine dies first, we still require some hooks to clean up the cache in the path. More to come. When VBO's are used, these will be a leaked if the path is destroyed after the engine. Reviewed-by: Samuel

| * Fixed miter joins generated by the GL2 engine stroker.Kim Motoyoshi Kalland2009-11-261-17/+36
| | | | | | | | | | | | | | | | | | | | The stroker generated two points for each miter join, one on the convex side of the join, and one on the concave side. For sharp joins between curved segments, the point on the concave side could end up poking out of the stroke. This was fixed by generating one point on the convex side only. Reviewed-by: Trond
| * Fixed round joins generated by the GL2 engine stroker.Kim Motoyoshi Kalland2009-11-251-49/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | Complete circles were generated at every round join, so if the join were close to a flat cap, the circle would extend beyond the flat cap. This was fixed by generating arcs rather than complete circles. Likewise, round caps are now semi-circles instead of full circles. I also removed some unnecessary calculations when generating square caps. Reviewed-by: Trond

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We always queried the client for its GLX extensions and used them blindly, even though they might not be available in the server. Also fixed the extension string check itself. We used simple sub-string search, which could potentially break if one extension name is a sub-string of another.

| | * Fixed extension checks and usage of the GL 2 engine on old X11 systems.Trond Kjernåsen2009-11-162-25/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a regression from 4.5, where exporting a GL capable display from an old X11 HP/Sun workstation to a modern Linux machine causes crashes and lots of X11 error output. Just relying on the client GL version number is not enough under X11, since the server might only support GL 1.1 with non or very few extensions. Also, the extension checks worked a bit randomly since it checked for sub-strings which might or might not occur within one or more full extension names. Task-number: QTBUG-5853 Reviewed-by: Kim

| | | | | | | | | | The GL2 paint engine adds a (0.49,0.49) pixel offset when doing aliased rendering. But this assumed if it was doing aliased rendering then multisampling was disabled.
