Bug report

Bug summary

The new antialiased image code appears to not handle zoomed images correctly.

attn @jklymak

Code for reproduction

from pylab import *
plt.rcdefaults()
fig, axs = plt.subplots(1, 2)
axs[0].imshow(np.random.rand(10, 10))  # now defaults to interpolation="antialiased"
axs[1].imshow(np.random.rand(1000, 1000))
axs[1].set(xlim=(-.5, 9.5), ylim=(-.5, 9.5))
plt.show()

Actual outcome

Run with mpl master (or anything after #13724 was merged).

Expected outcome

The right image should also be rendered using "nearest" interpolation.
