Problem: We really want to fit Gantt's on particular paper sizes (def. landscape A3); however, using the paperSize option doesn't really work as the output (font size, row heights, etc.) end up being too big and not suitable.
And for the majority of the time, paperSize set to auto creates an output (font size mostly) too small.
Rock and a hard place...
Solution 1: When pdf.paperSize is not set to auto i.e. A3, A4, etc. Allow a percentage scaling to be set, ideally individually, on X and Y.
Solution 2: Scale fonts and scale timeline on X axis maintaining taskList width.
Ultimately, get a large plan to fit on landscape A3.
