*This function is used to detect the current selection setting
* based on the values in the x0, y0, x1 and y0 fields.
*
* One of the most confusing parts of this function is why the array
* is built at the beginning. What needs to happen here is that we
* should always check the current selection to see if it is the valid
* one. While this is a performance improvement it is also a usability
* one during the cases where things like selections and drawings match
* size. This way buttons change less 'randomly' (atleast in the eyes
* of the user). To do this an array is built where the current selection
* type is placed first, and then the others in an order from smallest
* to largest (this can be configured by reshuffling \c test_order).
*
* All of the values in this function are rounded to two decimal places
* because that is what is shown to the user. While everything is kept
* more accurate than that, the user can't control more acurrate than
* that, so for this to work for them - it needs to check on that level
* of accuracy.
*
* @todo finish writing this up.
