How to set the data on an ImageData struct?

[tversteeg]

I know I can create image data by doing:

let image_data = context.create_image_data(width, height)?;

And applying it on the context with:

context.put_image_data(image_data, 0.0, 0.0)?;

But how can I actually change the values of the pixels of the image_data object? No functions for it are exposed and the .data field is private.

It seems we're missing the data getter. Could you send a pull request for that?

Is this good? #377
