[PATCH v2 0/2] MR244: winex11.drv: Keep GLX pbuffer alive while its drawable is used

[Paul Gofman (＠gofman)]

Other drawable types are ref counted and destroyed only when nothing (e. g., existing contexts) reference them anymore, making sure that if we have a context referencing drawable the GLX drawable is still valid. That was probably left behind for PBuffers.
