Backporting JDK-8369561: sun/java2d/OpenGL/DrawBitmaskImage.java#id0: Incorrect color for first pixel (actual=ff000000) and JDK-8378201: [OGL] glXMakeContextCurrent() drops the buffers of the unbound drawable.
This PR works around a Mesa bug (mesa#1001) where glXMakeContextCurrent() corrupts buffers when using raw X Window IDs.
For parity with Oracle JDK.
The PR is not clean because of a conflict in the year of the copyright in the header of "src/java.desktop/unix/native/common/java2d/opengl/GLXSurfaceData.c", which is trivial in nature.
Ran related tests on linux-x64, linux-aarch64, macos-aarch64 and windows-x64:
make test TEST=test/jdk/sun/java2d/OpenGL/FlipCoexistTest.java
make test TEST=test/jdk/sun/java2d/OpenGL/MultiWindowFillTest.java
make test TEST=test/jdk/sun/java2d/OpenGL/DrawBitmaskImage.java
