Previous attempts to clean this up followed similar logic to the
circle and rect types of imagemaps. However, in reality, we have
many image maps in our content that have negative values for poly
coordinates. While this isn't logical, breaking them so loudly
in the page isn't desirable.
This change then removes the check for positive value and passes
along the negative coordinate.

If a user provides a non-numeric coordinate in an image map, it
results in an unhandled exception. This change detects the incorrect
coordinate and warns the user with an error message.
This also cleans up a type casting that was old fashioned.

PhanUndeclaredVariable is reported, because the vars are not declared
outside of the loop and only conditional inside the loop.
The condition is run on first loop, so it is always run and the old code
works.
Declare the vars to make them visible before the loop
