Allow different background color of tablatur numbers
The tablatur numbers are set with white background color. It would be great if it is possible to choose a different color, so notes can be integrated in documents with non-white background (e.g. dark color themes). It was possible (so not easy ;-) to adjust the color for the other objects. But I did not find a way of changing the background color. It should not be transparent so that it separates the number from the lines. But it would be great, if the white background can be overwritten or tweaked somewhere.
I added an example that shows the white boxes around the numbers in the tablatur.
