Add ability to color SimpleFillSymbol hatching in Javascript API

Idea created by deleted-user-1T_bOHag6M8d on Oct 10, 2013

    Currently, Style types for the SimpleFillSymbol in the ArcGIS Javascript API other than STYLE_SOLID and STYLE_NULL use a PNG image for hatching. This means that all hatching is colored black and is unchangeable. As unappealing as I find hatching to be, my users desire it in their web applications and they desire the ability to have colors other than black.
