- display: GraphicsWindowProc should have a virtual destructor,
as it's meant to be subclassed.
- express: set_matrix_view helper should always fail an assert
when 'size' is wrong, even on release builds.
- express: Fix filename capitalization on some #includes.
They're normally Windows-only, where case doesn't
matter, but it's better to be consistent.
- gobj: Fix typo.
- particlesystem: Remove BaseParticle::_last_position.
Last position is tracked by PhysicsObject now.
- windisplay: Heed warnings about casting bool to (PVOID).
Also, per MSDN docs, SPI_SETMOUSETRAILS uses the
uiParam argument and ignores pvParam, so pass the
_saved_mouse_trails value in that way.
