The question: Is there a way to support changing point_count in animation?

Possibility 1: If the animation detect point_count changes from xx to x+1, maybe we can make a "growing" effect by lowering the iteration of point_count x by some low percent dependent on speed of the animation, and increase the iteration count of point_count x+1 by the same amount.

Example: point_count = 3 is with 50000 points wants to become point_count = 4
First frame point_count = 3 with 50000 points, point_count = 4 with 0 points
Next frame point_count = 3 with 45000 points, point_count = 5 with 5000 points
etc.

Possibility 2: Is possibility 1 doesn't work, should we just decrease the opacity of the point_count x fractal as we increase opacity of the point_count x+1 fractal?

The flam3 algorithm generally has a way of keeping track of points and correlates a high number with high "density". This could be represented by an integer representing number of times a point repeated itself in the same spot.

Challenge: how to represent a float value in the unit circle of radius 1 as an integer pixel.

Easy potential fix: In the utils.py file, point_to_image_mat function currently takes a matrix of float points and creates a width by height sized matrix of zero's and one's. It can be changed to Increment values of colliding pixels instead of setting them to 1.

The mat_to_color function can then choose colors and opacity of pixels based on values from 0 to n.

Proposal: Test an implementation with various scaling function to set opacity and color in mat_to_color
