My continuing work on a bounding box for plcolorbar requires a bounding box calculation for plbox which lead me to discover annoying inconsistencies in the various idiosyncratic methods used to determine superscript/subscript offset and font size scaling factors by the various device drivers.
I implemented plP_script_scale to provide a consistent PLplot core method of obtaining those scaling factors which was an improvement on all idiosyncratic methods. Furthermore, as of revision 11804 I have replaced the idiosyncratic method with the plP_script_scale method for almost all of our device drivers. The exceptions are wxwidgets and other plfreetype-based drivers where I invite someone else to convert from the idiosyncratic to plP_script_scale method of determining offset and font size scale factors since I don't understand how those scale factors are currently determined for such drivers. (There seems to be component of the calculation both in plfreetype.c as well as in wxwidgets.cpp. I don't understand how those are supposed to fit together, and I don't have the time to figure it out.) In sum revision 11804 is a good stopping point for this mini-project for me. Now that I have consistent results for exponent placement for most device drivers, I plan to return to finishing the bounding-box calculation including inverted tick marks, numerical tick labels, and exponents for plbox, and the overall title for plcolorbar.
