mixing signed and unsigned types in comparison can end up having
unintended results. for example:
if (-1 < 1U)
printf("true\n");
else
printf("false\n");
previously we silenced these warnings, instead just fix them properly
via necessary casting, and in cases where the value cannot be negative
(e.g width/height members) make them unsigned.
