[jira] Commented: (HARMONY-5338) [classlib][awt] Performance improvement for XGraphics2D

["Mark Hindess (JIRA)" <ji...@apache.org>]

Mark Hindess commented on HARMONY-5338:
---------------------------------------

I get UnsatisfiedLinkError running some swing code now because XSetClipMask is undefined while loading libgl.so.  This library should be linked against X11 libraries now so I've checked in a fix that works for me as r611545.

> I would like suggest performance improvement for XGrraphics2D. I've altered XGraphics2D's draw and fill methods with using JNI calls instead using X11Wrapper. It gives significant boost, for example: up to 5 times on drawRect and up to 10 times on fillRect operations.
