The native render function incorrectly determines that things are not in the viewport at high lat or long values (eg 151), this seems to be due to an integer overflow in CoordBox::center() which uses (BottomLeft + TopRight)/2 to calculate the center of the CoordBox

The attached patch resolves this, at least in my testing.

(In [10406]) ADD : revised OSB format. Allows to use large map files directly from disk with low memory footprint.
FIX : Native render doesn't render anything at high lat/long values (Closes #1135)
FIX : Expand tables in the properties dock to the available width by default (Closes #1136)
