Description

https://github.com/matplotlib/mplcairo/blob/master/ISSUES.rst mentions that there is an issue with "Invalid dpi manipulations in vector output". Is there an easy workaround for this?

Also, thanks for developing this backend! I don't understand all the details of how fonts are handled internally but mplcairo seems to be giving me better looking text!
