Subject: [PATCH] cocoa-cb: fix hwdec when drawing off-screen

drawing off-screen failed because we didn't have a valid context. the
problem is we force off-screen drawing because the CAOpenGLLayer refuses
to draw anything while being off-screen. set the current context before
starting to draw anything off-screen.

Fixes #5530
