Is your feature request related to a problem? Please describe.
I currently use a decent amount of Progress Textures to create a unique looking UI, but I am unable to use Sparks on the Progress Textures, and is therefor forced to use an additional Progress Bar to create a spark. With the decent amount of WeakAuras used in my UI, this creates an extra amount of close to useless auras only serving 1 purpose.

Describe the solution you'd like
I would like Sparks, as they exist for Progress Bars added as an option on Progress Textures, but understand that the solution is complicated, taking circular textures into consideration.

Describe alternatives you've considered
I'm unsure of any other proper way to do this, without using a bunch of on init functions to solve a somewhat simple problem, which I think would just create a bigger mess than my current problems.
Perhaps split Progress Textures into 2 different categories, Horizontal/vertical and circular, enabling different settings for each?
