Constant ovr_sys::ovrProjection_ClipRangeOpenGL

pub const ovrProjection_ClipRangeOpenGL: ovrProjectionModifier = 0x08;

Enable if the application is rendering with OpenGL and expects a projection matrix with a clipping range of (-w to w). Ignore this flag if your application already handles the conversion from D3D range (0 to w) to OpenGL.
