Actionbar Spell proc overlay

[feraldrood]

I want to find a way to change the scale and texture of the spellactivationoverlay (shiny gold box) around my icons on actionbars. Any help getting pointed in the right direction would be appreciated.

I am using a masque skin which makes my icons smaller than default, this is great- however the cooldown spark and glow around proc'ed abilities is still set to default scale which looks horrendous

not sure where to change these things, halp!

thanks
