...by constructing ImmutableBitmap directly from SkImage. This is a huge optimization for the case when content of canvas is painted onto another canvas, as it allows pixels to remain in GPU memory throughout the process. Fixes performance regression on https://playbiolab.com/ introduced by switching to GPU-backend for canvas.
