World axis lines with additional styling

The current default grid has a bit wider lines per 0.5 units, I suggest making the 0,0,0 lines per axis have a special style.
Could be a bit wider, also have a solid shared color or RBG axis-wise :)

Sounds great! ImPlot does have something similar, we should definitely implement it :)

Hi @dimateos, I'm converting all feature discussions to issues since GitHub has better support for task tracking (and copilot agent execution) with issues. This discussion was converted into #108
