ListDensityPlot with irregular data and InterpolationOrder

This is not explicitly documented (or at least I could not find any 
mention of it), but from looking at the plots it seems to me that with 
ListDensityPlot (and related functions), an InterpolationOrder higher 
than 1 only work with data that lies on a regular grid.

So for example the following data cannot be plotted with 
InterpolationOrder higher than 1:

data = {#1, #2, Sin[#1] Sin[#2]} & @@@ RandomReal[2 Pi, {100, 2}];

Is this correct?
