Screen -> MakieScreen (abstract type)

Is this all it takes to support the latest Makie? If so, that would be great news :)

I tried this patch, and the tests for QML.jl pass.

Unfortunately, the Makie examples from https://github.com/barche/QmlJuliaExamples don't seem to work. I tried opengl/makie.jl and opengl/makie-plot.jl, both failed with this error message:

MethodError: no method matching GLMakie.GLAbstraction.ShaderCache()

Closest candidates are:
  GLMakie.GLAbstraction.ShaderCache(::Any, ::Dict{String, Vector{String}}, ::Dict{String, Dict{Any, GLMakie.GLAbstraction.Shader}}, ::Dict{Any, GLMakie.GLAbstraction.GLProgram})
