Dropping X11 VCL backend

[Chris Sherlock]

Hi all, 

I am interested in knowing the future of the X11 VCL backend now that we have a Skia backend. Are there any plans afoot to remove it and just go with the Skia backend? 

If not, may I ask the reason? It seems maintenance heavy. 

If we are, do we have a potential release where we believe that Skia is stable enough to use and remove the X11 backend?
