[Gdal-dev] support for ERDAS pyramid layers

[kenboss]

I'm wondering whether support is eventually planned for ERDAS Imagine pyramid 
layers (.rrd files).  

The Supported Formats documentation states that "The current implementation 
ignores pyramid levels", implying that perhaps future implementations will 
support them?  

Later in the same document I find the line "Erdas Imagine supports external 
creation of overviews (with gdaladdo for instance)."  Does this mean to say that 
I can actually cause Imagine to read GDAL's .ovr files by some means?
