* Fill incomplete images in SkCodec parent classGravatar msarett2015-10-09
Rather than implementing some sort of "fill" in every SkCodec subclass for incomplete images, let's make the parent class handle this situation. This includes an API change to SkCodec.h SkCodec::getScanlines() now returns the number of lines it read successfully, rather than an SkCodec::Result enum. getScanlines() most often fails on an incomplete input, in which case it is useful to know how many lines were successfully decoded - this provides more information than kIncomplete vs kSuccess. We do lose information when the API is used improperly, as we are no longer able to return kInvalidParameter or kScanlineNotStarted. Known Issues: Does not work for incomplete fFrameIsSubset gifs. Does not work for incomplete icos. BUG=skia: Review URL: https://codereview.chromium.org/1332053002
