The interface to return bin boundaries and sampling hints for plotting in RooHistPdf and RooHistFunc doesn't consider that the histogram variable might be a transformation of the variable for which the bin boundaries or plot hints are requested. This commit improves the situation by implementing an algorithm that assumes that plot variable and histogram variable are linearly related, and numerically figures out the inverse transformation for transforming histogram bins to plot bins if needed. If the transformation is not linear, the RooHistFunc or RooHistPdf won't be correctly plotted either, but linear transformations are very common, even explicitly via the `RooLinearVar`, and supporting those is already a good improvement in user experience. Closes root-project#13030.

If the transformation is not linear, the RooHistFunc or RooHistPdf won't be correctly plotted either, but linear transformations are very common, even explicitly via the

The plot from the reproducer in the original issue does now look like this:
