* Even when the pts are restricted to 32K values, we can still overflow computingGravatar reed@google.com2012-08-06

* If we lose precision computing sum of the dash intervals, then we can have theGravatar reed@google.com2012-08-06

To fix this, we just pin the loop counter, and if we exhaust our intervals, we just treat the phase as 0. Not precisely the exact answer, but we aren't going to draw this dash correctly anyway, since it contains massive interval values that will be imprecise given our current float implementation.

* Always store pixels of mutable bitmaps when recording a SkPicture.Gravatar djsollen@google.com2012-07-27
| | | | | | | | | | | | | | | | | | | | | | | Prior to this CL mutable bitmaps only saved a copy of their pixels if a flag was set at recording time. That flag has been removed and the default behavior when recording a mutable bitmap is to make a copy of it's pixels. This is the only way to ensure that the pixels are not manipulated before we playback their contents. However, enabling this behavior breaks the recording of extracted bitmaps in SkPicture. This is because we currently cache bitmaps within a picture based only on their pixelRef. This results in false positive cache hit when drawing an extracted bitmap as it shares a pixelRef with its orginating bitmap. Therefore we must update the index of the bitmap cache to be both the pixelRef AND the size and offset of the bitmap using those pixels.

* Refactoring how SkDeferredCanvas manages mutable bitmapsGravatar junov@chromium.org2012-07-25
| | | | | | | | | | | | | This CL makes the SkGPipe flavor of SkDeferredCanvas properly decide whether to flush or record mutable bitmaps. The flushing is now managed by conditionally switching the canvas to non-deferred mode, which avoids an unnecessary transient copy of the bitmap.
