At first, this is <w>nice</w> util ;)
When I create a wave effect with only Scales by X and Y. I want something just like resizing an icon in text from its middle/center. I have set CurveX and CureY, set Pivot X = 0.5 and PivotY = 0.5 and named this wave effect like 'alert'. Using this: "Some icon <w=alert><q=cross></w> sized." So, it is scaled from middle by pivot Y, but NOT from center by pivot X.
PS. when I try it with a char from font ("Char <w=alert>A</w> sized") - it is ok.
PSS. this in UI
