29850	Poor Window Support for RowRange Frames	Daniel Fuchs	nobody	"The current RowRange frame is missing handling for several cases.

None of the following are currently supported:
RowRange(start=-2, end=-1)
ROWS BETWEEN 2 PRECEDING AND 1 PRECEDING
RowRange(start=1, end=2)
ROWS BETWEEN 1 FOLLOWING AND 2 FOLLOWING

It's also missing support for EXCLUDE.
ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING EXCLUDE CURRENT ROW
