The Colorize and Tint drawing modes

These two modes modify the color of the pixels:

* The Colorize mode adds the A color while respecting the pixel luminosity of the source image.

* The Tint mode also adds the A color but respects the saturation as well as the luminosity. The more a pixel is close to a gray, white or black color (with all the shades they contain), the less effect the color change will have.

This is visible in the drawing areas corresponding to the cloud : they are more affected by the Colorize than by the Tint mode. Here the A color is red.
