\brief This function is used to detect the current selection setting
based on the values in the x0, y0, x1 and y0 fields.
\param base The export dialog itself
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

The first thing this function checks is to see if we are doing an

instance of it that will handle everything for us. If there is a
units change, we also assume that everyone is being updated appropriately
and there is nothing for us to do.
If we're the highest level function, we set the update flag, and
continue on our way.

(call to the _pt ones for x0 and x1 but just standard for xdpi). The
xdpi value is saved in the preferences for the next time the dialog
is opened. (does the selection dpi need to be set here?)
A check is done to to ensure that we aren't outputing an invalid width,
this is set by SP_EXPORT_MIN_SIZE. If that is the case the dpi is
changed to make it valid.
After all of this the bitmap width is changed.
We also change the ydpi. This is a temporary hack as these can not
currently be independent. This is likely to change in the future.
