[OpenJDK 2D-Dev] Xrender GC leak fix

[Clemens Eisserer]

Hi,

The XRender pipeline was leaking GCs which are generated on the java-side.
Instead of trying to clean it up at the java-level, I now simply use
Java_sun_java2d_x11_XSurfaceData_XCreateGC which sets the javaGC field
in xsdo,
which is already freed automatically at surface-dispose time.

Thanks, Clemens
