Test behaviour of scaleX and scaleY.
Merge.
A few createGradientTests.
Faster code paths for little endian data buffer operations, and writing multiple ints and floats.
Reduces object allocation in the remoting deserializer.

Objects returned by '_readMatrix', '_readRectangle', etc. reuse objects so we must never leak references to them.
GFX frames use getters and setters for the 'matrix' property, setters copy individual members of the matrix so it is safe to assign temporary matrices. Getters return references the internal matrix so the returned value is safe to read but not write.
Add a quick description of available shortcuts to the inspector.
Default DataBuffers to default endianess.
UI improvements.
Fix type-o when reading color matrices.
Make sure to copy color transforms.
Fixes renderable text's handling of matrix and rectangle parameters.
Add acid tests to ref tests.
