* Fix for Ovals/RRects on N4 missing interior rectangles.Gravatar jvanverth@google.com2013-07-02
| | | | | | | | | | | | | | Clamp square of gradiant length to non-zero value so it can be passed to inversesqrt(). Also adds some fixes to rrect setup to avoid crossing zero.

* Better method for rendering AA ellipses.Gravatar commit-bot@chromium.org2013-05-16
| | | | | | | | | | | | | | | | | | | | | | | This uses the standard ellipse equation as a signed distance test, and adjusts the result by the length of the gradient at that point to get a better approximation of the distance to the ellipse. It replaces the standard ellipse and roundrect shader renderers. Also adds a check to see if the curvature extrema of the stroke are less than the curvature extrema of the ellipse (i.e. the radius of curvature is larger). In this case, it's no longer an ellipse and we can't use this renderer. Only supports stroking for near-circular ellipses.

* Add GPU support for roundrectsGravatar commit-bot@chromium.org2013-04-25
| | | | | | | | | | | | | | | This uses the OvalRenderer to render roundrects as "stretched ovals." It adds an additional shader that handles the straight edges of ellipsoid roundrects better, and uses the circle shader for roundrects where the two radii are the same. Only axis-aligned, simple roundrects are supported. Handles fill, stroke and hairline.

* Fix non-uniform scale and stroked ellipsesGravatar commit-bot@chromium.org2013-04-19
| | | | | | | | | | | | | | | | Strokes were not being scaled properly for ellipses -- the view matrix was being reset before the scale factors were being applied. Scaling the stroke has been moved up higher in the process. Also applies some optimizations suggested by robertphillips.

* Disable GPU acceleration for narrow ovals. Gravatar jvanverth@google.com2013-04-16
| | | | | | | | | | | | GPU anti-aliasing is currently not correct for ellipses where the ratio of long axis length to short axis length is greater than 2 (see https://code.google.com/p/skia/issues/detail?id=1249). This disables the GPU path for those cases. Review URL: https://codereview.chromium.org/13925015/ git-svn-id: http://skia.googlecode.com/svn/trunk@8694 2bbb7eff-a529-9590-31e7-b0007b416f81

* Shader optimization for ovals.Gravatar commit-bot@chromium.org2013-04-11
| | | | | | | | | | | | | | | | Previously we were setting a center point as an attribute across all vertices, then using that with the interpolated position to compute an offset. However, because the offset computation is linear, we can just set the appropriate offset at the vertices and let the rasterizer interpolate it for us.
