PI, drawing and editing fixes for shapes and materials.

IKNinja-1841 - Cannot change webgl shape with LinearGradient and RadialGradient to solid color.

IKNINJA-1851 - Cannot draw webgl shapes with Linear/RadialGradient material.

IKNINJA-1864 - PI doesn't update the color of shape if WebGL material switches to Flat.

IKNINJA-1886 - Gradient edits not applied to WebGL Stage object.
