* Implement gradient brush similar to PathGradientBrush (#969)
A gradient brush implementation that works similar to
System.Drawing.Drawing2D.PathGradientBrush.
This fixes#969, but only convex paths are supported for now.
* Update submodule to add test fixtures for #989
* Performance optimization
Use LengthSquared() instead of Length() when it's possible.
Avoid unnecessary ordering of elements.
* Avoid using LINQ in a hotspot
* Validate arguments for the public constructor
* Implement IDisposable and ensure inheritance calls base
* add ImageProcessingContextTests and move some other test classes
* loosen up tests and leave TODO notes
* disable multitargeting + TreatWarningsAsErrors to for fast development
* Check if image is disposed
in significant Image and Image<T> methods
* Mutate / Clone: ensure image is not disposed
* Revert "disable multitargeting + TreatWarningsAsErrors to for fast development"
This reverts commit 9ad74f76f6.
