In JavaFX 26 build 5, under bug id JDK-8365576, we switched to Metal as the default rendering pipeline with the plan that it would be reverted to OpenGL after 7 builds.

This task is to implement that reversion in the build done on 9th Oct 2025, which is expected to be build 12.

So this can be done any time after the repo has been tagged with 26+11 for build 11 on Oct 2nd and before the repo is tagged with 26+12 on 9th Oct, which is expected to be build 12.
