Fix possible out-of-bounds access when making distance fields
While extremely unlikely, there is a theoretical possibility that
the '0' glyph of a given font will have a width or height of 1 pixel,
in which case the (x + 1) / 2 way of getting the center would give us
an out of bounds pixel. We just default to true in this case, since
we cannot make any assumption based on the 0 glyph if it doesn't make
any sense. If the image is invalid, we default to false.
