Faster Linear Transforms (#1591 )

* Attempt to use same weight generation algorithm as resize.

* tests pass

* Identical output

* Update LinearTransformKernelFactory{TResampler}.cs

* Use new low allocation iterator

* Migrate projective transforms.

* Optimizations

* Smaller kernel

* Fix sampling accuracy

* Finalize and update refs

* Revert unnecessary changes

* Remove enumerator

* Actually save output for debugging.

* Use custom test png encoder for reduced memory environments

* Convolution should use scaled vectors

* Update TestEnvironmentTests.cs

* Try using doubles

* Moar double precision

* Fix radius calculation

* Test if issue is SIMD related.

* Detect runtime to determine pipeline.

* Fix stack overflow

* fix condition

* Try simplified scalar run

* Simplify unpremultiply scalar

* Update Numerics.cs

* Fix runtime environment

* Update ImageSharp.csproj

* Duplicate the caller with scalar versions

* Update method name, exclude from coverage.

* Don't save output during coverage tests for perf.

* Update src/ImageSharp/Common/Helpers/RuntimeEnvironment.cs
