commit 60d91a56430f55128003f2a5331db5390fcd2663
Author: Michael Meeks <michael.meeks at collabora.com>
Date:   Wed Sep 16 09:13:11 2015 +0100

    Squash 4x patches for quicker testing.
    
    tdf#94213 - cleanup associated GL contexts properly when DCs released.
    
    Change-Id: I6b9fb899777d8e460999ac3ff038a1302e434bb5
    
    tdf#94006 - need an explicit dispose for slideshow's GLContext.
    Fixes crasher exiting slideshow.
    
    Change-Id: I14b6a2c1abc946f590bf91cab19099753172fd95
    
    tdf#94252 - avoid switching contexts un-necessarily to reduce flicker.
    
    Change-Id: Id4ac387174fa03c5886a990d89fd53a4f18db11c
    
    GL paint-flushing guard re-work.
    
    Unfortunately, since we can have 2x SalGraphics' on a OutputDevice,
    and one of these can be a printer - things got very confused around
    which context to glFlush. This de-tangles the various reference-counts.
