[Bug]: savefig(..., transparent=True) does not make inset_axes transparent #22674
Description
Bug summary
All's in the title.
Code for reproduction
from pylab import *
gca().inset_axes([.1, .2, .3, .4]); savefig("/tmp/test.png", transparent=True)
# then display /tmp/test.png with a viewer that distinguishes between white and transparent: the inset axes is not transparent.Actual outcome
Inset is not transparent.
Expected outcome
Inset is transparent (... well, admittedly I guess whether one wants this or not may be figure-dependent?) (mildly relatedly, see also #10023.)

I'm surprised that the regular
Axeswas made transparent in the first place, but apparently that's what it's supposed to do.sramesh750 commentedon Mar 23, 2022
I could start working on this issue!

@sramesh750 Go for it!
transparent=Trueshould make all Axes transparent. Should more special needs arise, we can still add more options liketransparent='figure'later, but I would hold that until someone asks for it.rcomer commentedon Feb 25, 2023
Closed by #24816 I think.
