I have a project with hundreds (~500) of figures that are generated by MPL. I have a command in the conf.py to tell MPL to only generate PNG files at 80 dpi

plot_formats = [('png',80)]

but when I run the build, I get an error like

C:\Users\Belli\Documents\Code\CoolProp\Web\Fluids\trans-2-Butene.rst:19: WARNING: image file not readable: Fluids\../_build/plot_directive/Fluids/trans-2-Butene-4.pdf

for every single figure in my project.

Of course the PDF isn't readable since it shouldn't be being checked in the first place! I believe this is a regression since 1.2 or so (not sure of the exact revision though).

Hope a guru can chime in with wisdom!
