RFR: 8358058: sun/java2d/OpenGL/DrawImageBg.java Test fails intermittently

[Phil Race]

Moving to open a number of graphics related tests, originally written to test the OpenGL pipeline.
These versions are "better behaved" than the versions that were in closed - mostly meaning they now
do things on the right thread and paint properly on demand.
As a result they now pass - at least on systems with correct drivers etc.
There are a few bugs to add to the issue list which I'll do right after submitting this.

I also extended these tests so as to run with the default pipeline on every system, not just OpenGL.
This mostly went OK except that I found one of the tests fails on macOS with metal.
I've had to add a new problem listing for that.
