Hi Andrew,
That's a good find re: pow(). In the comment at lines 277-283 I
mentioned that there was only a scalar variant of pow(). I wonder if
that was a limitation in some early version of GLSL I was using or
perhaps some driver bug/restriction. According to all the docs I can
find the v
Hi guys,
I haven't looked at the code in question in quite a while, but my recollection
is that the OGL (and D3D) pipelines treated all surfaces -- including opaque
ones -- as premultiplied because the OpenGL blend modes weren't flexible enough
to replicate the equations used in our software lo

Hi Sergey,
Do you happen to know the intent behind this original change from macosx-port?
http://hg.openjdk.java.net/macosx-port/macosx-port/jdk/rev/50b8fef5df7d
The commit message for that changeset didn't have much information; it just
said:

It's package-private because it's only accessed within the
sun.java2d.opengl package, and in general we strive to reduce the
visibility of classes/interfaces. The concrete GLX/WGL
implementations also live in that package, so there was no reason to
make it public.
There's probably no har

Hi Clemens,
The antialiased case is handled in super.validatePipe() (in the
SurfaceData base class), which in turn calls getMaskFill(). We
override getMaskFill() in OGLSurfaceData so that it calls
OGLPaints.isValid() to determine whether the given paint can be
accelerated in the antialia
