Feature Request: Warn when axis title or axis label goes outside of the plot area #3282
Description
Related to #3281 (but not the same).
When text goes outside of the plot area, usually the plot is less readable. It would help to have a warning when text goes outside of the plot area. In the example below, the x-axis labels appear to start at "b" and end at "I" because the text is cut off. It would help find unreadable figures if this resulted in a warning-- especially with automated reporting (like in knitr documents).
If implemented, a theme option to suppress the warning would be useful, too. It could be something like theme(warn.outside=TRUE), and it may have variants for warn.outside.axis.text, warn.outside.axis.text.x, warn.outside.axis.text.y, warn.outside.axis.title, warn.outside.axis.title.x, warn.outside.axis.title.y, warn.outside.title, warn.outside.subtitle, warn.outside.caption, and warn.outside.legend.
