Still use wxPreviewFrame size if it was explicitly specified

Browse Source 
Even though it's better to not specify the preview frame size at all,
the size should still be used if it was explicitly specified, but this
didn't happen any more after the addition of the call to Fit().

Fix this now by only doing the equivalent of Fit() if no size was
explicitly given.

Also add advice about not setting the size explicitly to the
documentation.
