This commit addresses two issues related to : 1. Noise and streaking artifacts in animations due to unconditional calls on every draw. 2. A caused by the keyword argument being passed to Matplotlib internals. The following changes have been made: - A flag has been introduced in the class to control when is called. - is now only called when the figure's layout is dirty, preventing unnecessary recalculations during animations. - The method in now only resizes the figure if the new size is different, preventing small oscillations. - The keyword argument is now popped in to prevent it from being passed to Matplotlib.

This PR adds an
animation.force_draw_idlercParam (default on) and uses it to gate a targeted FuncAnimation hook that swapsdraw_idleto full draws on interactive canvases, reducing backend redraw artifacts without affecting headless renders, while keeping the earlier layout convergence work intactCloses #488
Drafting for now as I am not happy with it yet.
