Stefanos A. 0d3ab7174c Fixed crash on 32-bit machines 
uint-to-intptr conversion must obey uint-to-int conversions on 32-bit
machines, otherwise an OverflowException may occur: conversions of
numbers over 2^31-1 must be declared as unchecked.

Fixes issue reported here: http://www.opentk.com/node/3418
