macOS support; agenda item ESC

[Thorsten Wagner]

Very interesting - does this means that there is no OpenGL support for macOS at present too? Or is OpenGL/Metal supported by using respective macOS library calls? If the latter is the case, OpenGL (and Skia) option within preference dialogs should be removed for macOS. On the oder hand dealing with deprecation of OpenGL would be no discussion is this case. OpenCL option does not seem to work properly on macOS - same reason?

It's important to differentiate between Skia (or OpenGL) and LO VCL backends 
using them. Currently the only VCL backends that use Skia or OpenGL are 
the 'win' and 'gen' backends, which means Skia or OpenGL can be used only on 
Windows or on Unix with the gen backend that ~nobody uses in practice.

Other VCL backends such as the Mac one can be presumably made to use these 
too. I haven't done anything with Skia related to Mac because I don't have a 
Mac.
