I need to be able to set point size when rendering point.
So I have added a mPointSize property to Pass and uses
it in the SceneManager and implemented it in
GLRenderSystem and D3D9RenderSystem (D3D7RenderSystem
get an empty function).
The joined patch is against 1.0.5 version
I could remake it against the ogre CVS HEAD if needed.
I will try to integrate point sprite support and then I
will add the other attributes needed.
Any suggestions/comments are welcomed
