[Rev 03] RFR: 8218973: SVG with masking is not rendering image with mask effect

[Bhawesh Choudhary]

> Root cause of issue is Specifying a image mask from GraphicsContextJava.cpp in WebKit was not implemented, so masking
> doesn't take place at all while rendering SVGRect. to fix this issue add implementation of function clipToImageBuffer()
> in GraphicsContextJava.cpp and send clip image to WCGraphicsPrismContext.java  While rendering in
> WCGraphicsPrismContext.java if image clip mask is available, use it for rendering using MaskTextureGraphics interface
> otherwise use usual way of rendering.
