drawImage() does not work when image source is another canvas object

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create first canvas
2. Create second canvas
3. Use first.drawImage( second,...). In IE will not work.

What is the expected output? What do you see instead?
Expected the same behavior as in other browsers, which are supporting canvas as 
an image source for drawImage

What version of the product are you using? On what operating system?
excanvas.js r73 on Windows 7, IE 8

Please provide any additional information below.
Seems like this behavior occurs in case excanvas expecting only <img src=""> as 
an image source for drawImage(). Possible solution is to check if passed image 
is another canvas object and perform a valid staff to process it correctly.

This would be extremely helpful to me.

as an alternative would be nice to have a posibility to pass image object 
instead of second canvas, so it will look like this:

var image = context2.getImageData(0, 0, canvas2.width, canvas2.height);
context1.drawImage(image, 0, 0, canvas1.width, canvas1.height);

but the problem is that excanvas.js doesn't have implemented any of 
getImageData,putImageData,createImageData 

so it would be very helpful to have them too.

Is drawImage technically possible even using IE's VML? 
If so this feature would be extremely useful.
