Wrong global context with multiple canvases and dynamic textures

[inear]

Hi!

When using multiple instances and updating textures the global active context can be wrong if loadContentsOf is fired before the global context has been updated. I solved it by adding a parameter to the texture object and assign it in the wrapper.

In the Texture constructor:

this.gl = gl;

and modify this method:

function wrapTexture(texture) {

return {
    _: texture,
    loadContentsOf: function(element) { 

        //set correct global gl
        gl = this._.gl;

        this._.loadContentsOf(element); 
    },
    clear: function() { this._.clear(); },
    width: function() { return this._.width; },
    height: function() { return this._.height; },
    destroy: function() { this._.destroy(); }
};

}
