Click canvas elements with explicit coordinates

[sroettering]

In my application I have a map that is rendered on a canvas. Now when I use the recorder to record some test cases for clicking on certain positions on the map the recorder just generates normal clicks which target like some corner of the actual element. For canvas elements in particular it would be nice to actually record the clicked coordinates.

Might already be implemented in #155

I'd really like to have this feature too. Has anyone worked on something similar?
