Hello Alexander Z, Chien, Guru
Please review the following fix.
JIRA: https://bugs.openjdk.java.net/browse/JDK-8160260
Webrev: http://cr.openjdk.java.net/~arajkumar/8160260/webrev.00
Issue: SVG images are not shown when rendering initiated in the context
of <img> or CSS background property.
Analysis: After r179335[1], WebKit started using
GraphicsContext::clipBounds from SVGImage::draw to eliminated
unnecessary rendering. Our JavaFX port doesn't implement
GraphicsContext::clipBounds and returns empty bounds which is (0,0 0x0).
Due to empty bounds, SVG image drawing is skipped. In order to implement
GraphicsContext::clipBounds, we need to get clip information from
WCPrismGraphicsContext object, but is not accessible from WebCore.
Solution: Added a shadow variable in GraphicsContextState to maintain
current clip information, it will be updated on each call to platform
clip API.
