Is there a way to pass sorting elements count without recreating the kernel?

Some tasks need to sort flexible elements count instead of hard set on initialization.

The count parameter is used to initialize pretty much every shader module and buffer in the radix sort kernel, I unfortunately don't see a clean way to update it dynamically.

It may be possible to achieve this by changing the ELEMENT_COUNT inside the shaders from a constant to a uniform value so it can be updated from the cpu, under the condition that the new count is lower than the initialization count. It won't really help on the performance however.

I believe recreating the kernel is currently the best way to go.
If applicable, you can also try padding the excess elements with the max integer value and only looping through the correct element count manually.
