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 Axes was made transparent in the first place, but apparently that's what it's supposed to do.

@sramesh750 Go for it!

transparent=True should make all Axes transparent. Should more special needs arise, we can still add more options like transparent='figure' later, but I would hold that until someone asks for it.
