Is your feature request related to a problem? Please describe.
I am building a bar with GTK4 and I wanted to have an animated battery visualization, which can only be done with cairo as far as I know.
Describe the solution you'd like
As stated by #80 , it seems like Cairo isn't really going to be ported to GTK4, so what about porting GLArea instead? This would enable GPU shaders instead to be run, which can be a nice alternative.
Describe alternatives you've considered
Either GLArea, Cairo or any other vectory rendering library would be good enough, but I am not sure if the last is even feasable.
Additional context
Nothing else to add for now
