Description
SingleQuerySqlGenerator and AggregateResultSetExtractor should support projection information, limiting the the columns loaded.
Actually tying this to the handling of projections might be a separate issue, although nobody would complain if it gets implemented with this one.

Research direction
Start by locating SingleQuerySqlGenerator and AggregateResultSetExtractor and reading how single-query loading currently determines its selected columns. Trace the projection information through the API-level loading path; done means both components use projection information to limit loaded columns without breaking existing single-query behavior.
