Cleanup:

* Remove several unused parameters
 * Fix several "comparison between signed and unsigned" warnings
 * Move variables into a more local scope where possible
 * Merge the conditions of some nested if-statements
 * Use an enum instead of some "magically defined" macros
 * Remove unused functions tooNearEdge and demoRequestStart
 * Mark function findSomethingInteresting as static
 * Use ARRAY_SIZE(array) instead of sizeof(array) / sizeof(array[0])
 * Get rid of some unnecessary casting from float to int
 * Mark several unused parameters with WZ_DECL_UNUSED for callback functions
