Mark Hindess commented on HARMONY-5394:
---------------------------------------

Dynamic loading of the libgl.so broke for me on linux.x86_64 after this commit.  I've fixed
it (and the ppc platforms) in r614168.  This is the second time you've broken awt for me recently
but these improvements are much appreciated.  ;-)

> I would like suggest performance and functionality improvements for XBlitter. This improvements
based on XRender extension and allows drawing Images with native affine transformations and
alpha composites. It also gives boost of drawing Transparent images up to 5 times as compared
with our current XBlitter implementation and up to 45 % as compared with SUN 1.5 JDK implementation.
