Aeroglass glrepeat support clean

[zoltanpillio]

We would like to use textures with GL_REPEAT instead of GL_CLAMP_TO_EDGE wrap mode.
In this code version TexturesHandler has a new getTextureIDReference method with an additional parameter to control wrap mode.

I took a quick look and it looks right. @amazingsmash can you check it too?

[amazingsmash]

I haven't tested either but all changes seem logic. Native implementation of GL seems complete.

I took a quick overview, and it looks right.

BTW, I'd like to remove the GL:: uploadTexture() method without the wrap parameter, and refactor all over around where this method is called. In short, I don't think that any wrap policy could be the default and it has to be set explicitly in all calls to uploadTexture().

@amazingsmash do you agree?

[amazingsmash]

I've already removed those methods, and added a little example over the Gran Canaria island of a repeated texture.

@amazingsmash I can't believe my eyes, you're working on Saturday! =o)
