* Fixed performance issue in QML clipping with OpenGL 2.0 paint engine.Samuel Rødal2010-09-281-4/+4
| | | | | | | | | | | | | | | | Change 4c515ceb fixed Intersect and Unite-clipping after doing setClipping(false), but also introduced a performance problem. If there was no pre-existing clip we'd convert IntersectClips to ReplaceClips, which is unnecessary since the paint engines already handle this correctly. IntersectClips can be handled much more efficiently in the OpenGL 2 paint engine for example. We only need to convert to ReplaceClip when someone has used setClipEnabled(false) which is anyways expensive and not recommended. Reviewed-by: Trond
* Fixed antialiased rasterization bug in raster engine.Samuel Rødal2010-09-283-7/+41
| | | | | | | | | | | When rasterization in the gray raster fails due to out of memory there might already have been a number of spans flushed. To avoid flushing these spans multiple times and thus getting overdraw artifacts we need to keep track of how many spans to skip when we redo the rasterization. This fixes the rendering error in arthur test paths_aa.qps Reviewed-by: Yoann Lopes
* Small optimizations the gray raster for 64-bit.Samuel Rødal2010-09-281-4/+4
| | | | | | | | | The gray raster uses long to ensure having 32-bit integers since it was originally designed to work on 16-bit platforms as well. On 64-bit platforms switching to use int instead of long gives a performance boost of ~10 % or so depending on the use case. Reviewed-by: Yoann Lopes
* Fixed floating point overflow issues in QRasterizer::rasterizeLineSamuel Rødal2010-09-231-60/+79
| | | | | | | | | | | | | | | | | Change 7c673a4cf64ba04 introduced some autotest failures in the fpe_steepSlopes test in QPainter. Since the other rasterizers all deal in a 26.6 fixed point coordinate space we should snap the line vertices to this to prevent floating point overflows due to very steep slopes. This also necessitates keeping track of four different slope / inverse slope increments for each of the four edges. This also fixes a previously QEXPECT_FAIL'ed test case.

* Fixed scaled point drawing with square cap in raster paint engine.Samuel Rødal2010-09-231-24/+17
| | | | | | | | | | | With a large pen width and a small scale, due to the hacky way we draw points (stroking a line from (x, y) to (x + tiny_amount, y)), we some times end up snapping these two points to the same in rasterizeLine(). If we instead apply the SquareCap before we do clipping / snapping we don't get this problem. Task-number: QTBUG-13429 Reviewed-by: Trond

* | Fixed drawing a large number of glyphs with the same font under GL.Trond Kjernåsen2010-09-212-8/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Our glyph caching system doesn't take GL texture size limitation into account, and assumes you can create an infinitely large texture. On top of that, the cache will never create a cache that is wider than 256, or QT_DEFAULT_TEXTURE_GLYPH_CACHE_WIDTH, which means we'll hit the texture size limit even faster. With this patch the entire texture is utilized. However, to fix in properly we need to support having multiple texture for each font engine. That will be fixed shortly (see task QTBUG-13784).
