Be able to directly apply a colour to some shapes

to apply a colour to a shape:
Current: you need to: select the shape, clic on a colour button, select the colour and validate.
Wanted: be able to set the current colour of a colour button to some shapes

Proposition: a new colour button. It will be divided into two parts: the first part is classical and allows to launch the colour selector ; the second part will apply the current colour of the button to the selected shapes.
