OpenGL and Cairo canvas not updated on pad color change

[ikletti]

Changing the color of footprint pads on the "Render" tab in Pcbnew is immediate when the default canvas is active.

In the OpenGL and the Cairo canvas, the change does not happen until another canvas is activated or the OpenGL or Cairo canvas is reloaded (i.e. pressing the F11 or F12 button). Using redraw (F3 button) does not initiate the color change.

This was first noticed on a Debian 8 / Kicad 4.0.2 production system.
