[PATCH] Request a WGL depth stencil capable pixel format by default until we have proper SetDepthStencilSurface support. Adding this function during the 1.0 code freeze is too risky as it requires big changes and likely unleashes a lot of bugs. This patch fixes a bunch of regressions in GTR2, Suppreme Commander and Call of Duty 2 and 4.
