Add separate event handler for touchcancel/touchleave ...

Now I've separated the handlers for touchcancel / touchleave, because in previous commit I've attached the touchEnd handler, but that wasn't correct - when touchcancel/touchleave is triggered, tap event must not fire.

Add listeners for touchleave and touchcancel.

Fix WebGLFilterManager to use renderSession.resolution ...

This will allow filters to at least fill up the desired screen real
estate.

There's still a further issue in that filters don't actually scale
themselves based on the resolution, however.

Fix RenderTexture and resolution compatibility ...

Fixes the bizarre drawing of RenderTexture's with a resolution greater
than 1.

I also noticed some incompatibilities between how properties were set
both on RenderTexture instantiation, and when the resize method is used.
I fixed these as necessary.

Fix for RenderTexture.resize ...

`RenderTexture.resize` method does not take into account the resolution
when updating `baseTexture`. In the constructor function
`this.resolution` is used to set the width and height. This fixes an
inconsistency in how those dimensions are set
