* Overhaul the image library, Phase I. The preps for our upcoming mipgen command line tool by adding filtering capabilities and unit tests for a new LinearImage class, which will subsume Image (deprecated). Filament's new image library is composed of three components: - LinearImage....simple 3D tensor of floats - ImageOps.......free functions for simple transforms - ImageSampler...high quality filtering The old Image class was a simple untyped data blob and is now deprecated. The new LinearImage class is always float32, and always stores pixels in packed scanline order. This makes it easier to implement image-based algorithms because they can be agnostic of the underlying format. Remaining refactorings: - Phase II will migrate imageio to LinearImage - Phase III will migrate all downstream tools to LinearImage - Phase IV will remove old the Image class * Image library code review feedback.
