Dynamic 2D Shadows

[Andru]

In svn version of ZenGL I have improved zgl_direct3d_all.pas and now these shadows works correctly through Direct3D9 render So, in near future I will try to make LightEngine 2D with Direct3D9 rendering, which will work with ZenGL.dll, i.e. not only statically.

Very nice! For me the difference between soft and hard shadows was a mere 7 FPS. On demo 3, objects near the top seem to go invisible. Seems like it may be a result of you destroying physics objects but not shadows.
