Note: Image resolution level indexes may differ from
* tile-component resolution index. They are indeed indexed
* starting from the lowest number of decomposition levels of each
* component of each tile.
*
*
Example: For an image (1 tile) with 2 components (component
* 0 having 2 decomposition levels and component 1 having 3
* decomposition levels), the first (tile-) component has 3
* resolution levels and the second one has 4 resolution levels,
* whereas the image has only 3 resolution levels available.
*
* @param rl The image resolution level.
*
* @return The vertical coordinate of the image origin in the canvas
* system, on the reference grid.
