The first Present post tries to explain what the extension does:

In short, it's a way of getting new window content onto the screen in a
vblank-synchronized fashion from a pixmap. This should allow regular X
applications to produce efficient and non-tearing updates, and when
combined with DRI3, will also allow direct rendering applications the
same features.

So, the fundamental purpose of the extension is to get bits from a
pixmap and stuff them on the screen. I called it 'Present', intending to
use the verb form and not the noun (as in I present you with this lovely
pixmap, please put it in my window). Some verb indicating the submission
of new contents is what I'm looking for here.
