FVWM: Force application to use my icons

[Walter Alejandro Iglesias]

Hello,

Is there a effective way to force applications to use the icon I set
with Style * Icon someicon.png?

I accomplished that for mini icons with:

Style * EWMHMiniIconOverride

But I couldn't with icons.  I've tried IconOverride,
Icon[Dont]DonateIcon, both settings fails.
