Fix canvas redraws during motion in figures with a Button or TextBox
During motion in figures with Button or TextBox widgets, the stored `color` and `hovercolor` values are compared with the current Axes facecolor. By default, the stored colors are each a string of a float, but the returned facecolor is frequently a tuple of RGBA values. The colors appear to mismatch, triggering a draw event with any motion in the figure. As a fix, convert both the color and facecolor values to RGBA format for comparison in case either value is stored in a different format.
