Optimized canvasrenderer and made it about 8-10% faster in my test runs.
Also removed unnecessary tags directly when the XML-file is loaded. This means
that this version of canvasrenderer only has about half as many objects in the array
as the last version, which should save quite a bit of memory. (With the current
test XML-file, the arraylength went from about ~900 000 to ~420 000)
