Irrlicht Engine

The Antialiasing in the demo is incorrectly set, while in DX works just fine, the value that is expected in GL doesn't seem to have any meaning.
It is an error which has been there for a long time already, and obviously hasn't been fixed. While in the release versions of Irrlicht, the antialiasing was meant to be enabled or disabled as a toggle, the SVN version used a value indicating the quality of the antialiasing used. In fact, it is more useful to have the antialiasing as a value, indicating the amount of samples we want to use. Hence, something like this:


Or any other aa value for OpenGL which works as expected, is the right way to go now. And works.

I think this was not properly updated when I changed the semantics of the field from bool to integer. DX has this special case '1' which means some magic anti-aliasing mode. Which is probably also not what is wanted, but works to some extent.

I fixed it (in 1.8 branch), but could not get AA for OpenGL even after the fix. Not sure whether my system has problem or still some other issue exists.

It is really a matter of inconsistency as well. It is mixing two working modes, either antialiasing as a switch or as a value, it should just stick to one, the one currently used, lucky it only affects the demo. The Antialiasing for both DX and GL works very well.
