Piano roll grid menu #21

Open swesterfeld opened 7 months ago

This PR adds support for letting the user set the grid size manually. It supports tuplets (we could not do this at all before), so for instance you can uses 1/8 triplet grids. It also supports small grid sizes, while being smart enough to not draw too many grid lines.

I've preserved the code we already have for automatic grid size selection. I believe that this can be nice, because you can zoom in, and as you zoom in the grid adapts to smaller and smaller grids. So with the PR, I added an explicit choice between grid mode "auto" (automatic grid size) and "manual" (user defined grid size).

As far as I know, you already have other code for computing grid lines (for the arranger) and you want my code and the other code be merged and shared between piano roll and arranger; so it would be great if you could provide your code.
