It has to do with how the math works for interpolating textures. It happens
with UV mapping everwhere. The example that is more often mentioned is
mapping a square texture to a trapezoidal plane. Look up some info on the
math behind how UV mapping works if you are really interested in why it is
happening and why there is no avoiding it on a simple plane.
The solution? Add more interior verts to your surface. Having more verts
makes for more UVs and less drastic interpolation of the texture map.

Subject: corner pin type of texutre placement in UV editor
ok... I've got a poly plane... I want to map it with a photographed texture
of a
sign thats not exactly straight on to camera. so I open up the UV editor
and pull some UV's around to line up the corners of the sign in the texture
with the
UV corners of my sign geometry. WHY does the poly object break the texture
along the
triangle facet diagonal line of the object? Try it assign a map to your
geometry
and pull a corner out it "folds" at the diagonal..
Is this a "feature" and why would you want this behavior. I seem to remember
this functionality
working differently in the past but maybe I just wasn't doing something this
extreme?
any ideas?

Where am I going, and how did I get in this handbasket!

stars in the sky and I thought to myself,
"Where the heck is the ceiling?"
