has no method 'vgSwapBuffers'

[nagualcode]

Hello,
I can get the clock example running, but many other fails like:

/node-openvg-canvas/examples/pathText.js:107
canvas.vgSwapBuffers();
^
TypeError: Object [object Object] has no method 'vgSwapBuffers'

Change those calls from "canvas.vgSwapBuffers();" to "Canvas.vgSwapBuffers();".
They're different variables.
