Comment 38 for bug 1566050

So with: changeset https://gerrit.libreoffice.org/34883, https://gerrit.libreoffice.org/34877 and https://gerrit.libreoffice.org/34841, and some more info on where these leaking pointers where created this is down to:

      1 LEAKED VCLPTR: P12OpenGLWindow created at OPERATOR= line -1 referred to from a PK6VclPtrI12OpenGLWindowE
      1 LEAKED VCLPTR: P12OutputDevice created at chart2/source/view/main/DrawModelWrapper.cxx line 114 referred to from a PK6VclPtrI12OutputDeviceE
      1 LEAKED VCLPTR: P13VirtualDevice created at svx/source/svdraw/sdrpaintwindow.cxx line 112 referred to from a PK6VclPtrI13VirtualDeviceE
     33 LEAKED VCLPTR: P13VirtualDevice created at RESET line -1 referred to from a PK6VclPtrI13VirtualDeviceE
     50 LEAKED VCLPTR: P13VirtualDevice created at unknown line -1 referred to from a PK6VclPtrI13VirtualDeviceE
    120 LEAKED VCLPTR: P12OutputDevice created at unknown line -1 referred to from a PK6VclPtrI12OutputDeviceE
    260 LEAKED VCLPTR:

That is down from 317 non-null VclPtrs on deinit in Comment 12 to 206 non-null VclPtrs (down by 35%).
