[Feature Request] dcc.Slider - Enable user to define slider direction

[Rory-Lambert]

I have an application where I am like to use sliders to crop an image (heatmap graph). The image's (0,0) is defined as the top left of the image. I'd like the y slider to start with 0 at the top, and end with the height of the image at the bottom. Currently, I cannot find a method to invert the slider to allow for the slider to go {top: low, bottom: high}, instead of the default {top: high, bottom: low}

Describe the solution you'd like
A slider where the direction from minimum to maximum could be swapped.

Describe alternatives you've considered
I tried setting the min to be higher than the max, did not work.
I've tried flipping the slider with CSS and the result is... erratic
