New Features

API Surface

• SKBitmap decoding improvements — Bitmaps can now be decoded as a specific format (size/scale, color type) and pixels can be replaced in a variety of ways.
• SKBitmap Index8 color type support — Better support for the Index8 color type. ❤️ @Tylerflick
• SKCanvas.QuickReject — Perform a fast bounds check before drawing to avoid unnecessary work.
• SKCodec incremental decoding — Codecs now support incremental decoding for progressive image loading.
• GRBackendRenderTargetDesc convenience members — Added Size and Rect properties for easier use.
• SKColorTable indexer — Access colors directly via an indexer.
• SKData as stream — SKData can now be used as a stream, which manages the lifetime of the underlying data.

Platform

• Views ignore device scaling option — All raster-based views (SkiaSharp.Views and SkiaSharp.Views.Forms) now have an option to ignore device scaling.
• SVG custom canvas sizing — SVG files can be loaded onto a canvas of a pre-defined size, ignoring the drawing size in the SVG file or handling files without a size set.

Bug Fixes

• Fixed SkiaSharp for Windows Mobile emulator and Xbox One.
