Allowing for Vsync to be disabled on DirectX desktop buils.
Fixed MaximumFrameLatency to be reset on ApplyChanges().
We now force the default MaximumFrameLatency when vsync is disabled.
Improved performance of the bounding box from a point cloud method.
Exposed PresentInterval on SwapChainRenderTarget so that VSync can be disabled if desired.
Removed the setting of MaximumFrameLatency from SwapChainRenderTarget, since this could override the setting from the GraphicsDevice.
Merge branch 'DirectX11VsyncDisable' of https://github.com/SickheadGames/MonoGame into DirectX11VsyncDisable
Added GetFrameLatency extension to PresentInterval.
GraphicsDevice now uses this extention.
Slightly clarified documentation.
Changed SwapChainRenderTarget to use new PresentInterval extention.
Added new TargetBlendState class.
BlendState class extended to support optional per-target blend states under DX.
Added overloaded BlendState.Dispose(bool).
