VideoTexture: Set format to RGBFormat by default.

[mrdoob]

Texture sets format to RGBAFormat if the user doesn't set it.
Would it make sense to set VideoTexture's format to RGBFormat by default instead?

I would say yes. All examples using VideoTexture right now set format to RGBFormat.

BTW: Would it also make sense to set minFilter to LinearFilter? Instead of this pattern:

var texture = new THREE.VideoTexture( video );
texture.minFilter = THREE.LinearFilter;
texture.format = THREE.RGBFormat;

it would be just

var texture = new THREE.VideoTexture( video );

@mrdoob yes.
@Mugen87 yes.

Although we usually use this pattern:

Texture.call( this, video, mapping, wrapS, wrapT, magFilter, minFilter, format, type, anisotropy ); 

this.format = format !== undefined ? format : RGBFormat;

this.minFilter = minFilter !== undefined ? minFilter : THREE.LinearFilter;
this.magFilter = magFilter !== undefined ? magFilter : THREE.LinearFilter;

this.generateMipmaps = false;

Implemented. Thanks!
