For once i haven't seen any resource that contains a 100x100 icon, but 
yes - in this case
we will ask OS to interpolate icon into sizes we know of and will return 
a set of sizes.
As for less accurate - i mean that in most cases (in all cases i 
observed actually) OS doing
much better job interpolating icons than we do. Plus it only works when 
we can get the
location of the file containing this resource and we will still have to 
implement a fallback
method when system says that path to resource file can not be resolved.
