You'll need to split your polygon up appropriately.

i.e. so all texture values fall between 0 and 255 (though watch for
glitches on the far right and bottom of your polygon with values of
255).

At first I didn't like the idea, but it is actually quite easy to do
and hasn't caused too much of a problem.
