NullPointer in BaseGraphics.drawTextureVO

[Daniel Zwolenski]

This is an older version, probably JFX from around jdk1.7.0_02.

I'm running it now on jdk1.7.0_21 to see what happens (takes about an hour
to get to the point of failure, which is why I didn't pick it up when I
wrote the code originally).

Unfortunately chunks of the system are broken when it runs on this newer
code. Lots of backwards compatibility breaks, especially visual ones with
CSS that just make it screwy. This is an old project and I don't really
want to be touching this code but they have this video capture bug which is
killing everything.

I take it there's no way to avoid the resources issue in the old JFX, it's
just a plain and simple bug?
