That cost is paid no matter what, no?

They're not the same.  Text is a vector format, and we can ignore how
it draws and just read out the geometry, for the purpose of drawing
text-shadows.  (In other words, we can just redraw the text in the
desired shadow color, apply the desired blurring, then composite it in
the right place in the visual ordering.)  That's quite a bit different
from handling images with transparent areas, whether the image is
vector or raster.
