From ac27d538af33ca8d67d3d88729f49c05793afda7 Mon Sep 17 00:00:00 2001 From: Nivesh Rajbhandari Date: Mon, 9 Jul 2012 11:43:36 -0700 Subject: 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.
