`RefractionMap` ⟶ `RefractionMapping`

Removed old Blender exporters.
Slim exporter is now Normal exporter (needs some testing).

CanvasRenderer/SVGRenderer: RenderableFace4 is now gone. Unfortunately it created more problems than it solved.
CanvasRenderer now with ShadingSmooth, or something along the lines...

There shouldn't be any change in functionality, just moved code around and clarified comments.

2d texture encapsulates bitmap, wrapping and minifying/magnification parameters.

Which reminds me, maybe also minifying/magnification options should be parameters in Texture object.

Though as defaults are "best" (LINEAR / LINEAR_MIPMAP_LINEAR = trilinear filtering), this would make sense just for special use cases like when trying to achieve "retro" look (like in Minecraft, http://gregs-blog.com/2008/01/14/how-to-turn-off-bilinear-filtering-in-opengl/ ;).

Changed materials a bit to look better with lighter environment map.

Added space to buttons HTML so that Firefox don't draw them sticked together.

Also re-added htaccess for BIN files.

Not sure about adding car models, they are quite big (even binary ones). To be removed if it makes troubles with git / GitHub.

Turns out it is working better over the real web than on localhost (where it seems loading is too fast for Chrome to pick up UI changes, so it queues them and shows them all just after loading is already finished).

Still not working properly - getting length of full content, this seems to be unreliable across browser / server combination.

Instead passing to callback JSON object with both total and loaded bytes, so this can be handled in the application layer:

{ total: bytes_total, loaded: bytes_loaded }

To be used e.g. like this:

loader.loadBinary( url, function( geometry ) { createScene( geometry ) }, path, updateProgress );

function updateProgress( progress ) {

    var message = "Loaded ";

    if ( progress.total ) {

        message += ( 100 * progress.loaded / progress.total ).toFixed(0) + "%";

    } else {

        message += ( progress.loaded / 1000 ).toFixed(2) + " KB";

    }

    $( "status" ).innerHTML = message;

}

Added a simple example for that.

Not anymore automatic, but also much less wasteful.

Has to be called in tandem with scene object removal:

    scene.removeObject( object );
    webglRenderer.removeObject( scene, object );

In WebGLRenderer transparent materials are now handled in the same pass as blended materials (resulting in better fake transparency ;)

The order of render passes is now following:

1. opaque materials with normal blending

2. opaque materials with additive blending
3. opaque materials with subtractive blending

4. transparent materials with additive blending
5. transparent materials with subtractive blending
6. transparent materials with normal blending

With growing number of passes it's possible it may be worth to do some pre-sorting, though it would have to be tested.

Current way is fairly cheap as if there are no corresponding materials in the pass, for loops just blast through (potentially many very cheap operations).

Pre-sorting would mean creating arrays on the fly in each frame (one expensive operation with effect on garbage collection, which especially Firefox is currently very bad at).

Added option to OBJ converter allowing to invert material transparency (some models interpret 0 as opaque and 1 as transparent).

Fixed SVGRenderer.
