Don't create an ortho matrix when the viewport is 0 in any axis. (#1504)

Browse Source 
* Don't create an ortho matrix when the viewport is 0 in any axis.
Not all compilers divide by 0 and return inf, some segfault.
The matrix is not used by anything when minimized, so it just needs to not be called.

* Better fix that always ensures the rlgl matrix is always valid
