* Fixed issues found by fuzzerGravatar commit-bot@chromium.org2013-09-13
| | | | | | | | | | | | | | | Last week, the fuzzer found a few numerical issue with filters and I had written some fixes for them. Here are the fixes with some unit tests. For senorblanco : So I figured out what was asserting when we'd get a 0 width "result" in SkBicubicImageFilter::onFilterImage(). Basically, if the "result" SkBitmap object calls SkBitmap::setConfig() with "width" and/or "height" set to 0, then the SkBitmap object will call SkBitmap::reset(), making the SkBitmap object's config invalid. At this point, calling SkBitmap::getAddr32() will assert, even without attempting to dereference the data pointer, because the SkBitmap's config is invalid. If height is valid, but width is 0, then this call to SkBitmap::getAddr32() happens directly in SkBicubicImageFilter::onFilterImage() a few lines lower and asserts right away.

* In image filters, apply the CTM and offset to the crop rect. This is ↵Gravatar senorblanco@chromium.org2013-08-27
| | | | | | | | | | | | | | necessary to compensate for both clipping applied by the compositor (communicated via the CTM) and for cropping applied in upstream image filters (communicated via the offset). This requires a few ugly conversions, since the crop rect is an SkIRect, and the ctm is an SkMatrix. I also had to offset the matrix passed to filter evaluation by drawSprite() and internalDrawBitmap() by the primitive position. This is the same offset that is applied when drawing the primitive, to compensate for the internal saveLayer(). Also apply the total matrix to the filter params in asNewEffect(), so that (for example) lighting params are offset by both the compositor clipping and upstream crop rects.
