SDK changes

General

[improved]

1. The LOD curve (max vertex count vs vertical screen size) has been improved by splitting it into two parts: linear from 0% to 100%, parabolic above 100%. This means more vertices than before for sizes up to 100% and the same amount for above 100%. The aim here is to help developers create less detailed LODs by letting them use more vertices than before. This new LOD curve is activated as the default one, and a debug option is available from the DevMode Debug menu to switch to the old curve values.
