Hi Everyone,
Please review the fix for 7181438.
This bug was introduced in 7u4b11, when macosx-port was integrated to
jdku7 by this changeset:
http://hg.openjdk.java.net/jdk7u/jdk7u-dev/jdk/rev/9dfe50f456be
Note that now we always set format to GL_RGBA. So opaque surface has an
alpha channel.
We handle this situation in: OGLBlitSurfaceToSurface,
OGLBlitSwToSurface, OGLBlitToSurfaceViaTexture,
but there is no check in OGLBlitSwToTexture().
I assume that code for alpha verification should be the same.

Webrev can be found at: http://cr.openjdk.java.net/~serb/7181438/webrev.00
Also note that CR 7177173 and 7124244 depends from this one.
