We have FuBarPlugin:GetFrame() but we don't have FuBarPlugin:GetMinimapFrame(). GetMinimapFrame() would look almost exactly like GetFrame(), except it should use pluginToMinimapFrame[self] instead of pluginToFrame[self].

Having both would facilitate tooltip implementations that don't use either GameTooltip or Tablet-2.0.

I've just used frame:SetScript("OnEnter", MyAddon.ShowTooltip etc, in order to use LibQTip-1.0. If there's an easier way that doesn't require access to the addon's FuBar and MinimapIcon frames then please let me know.
