gdalwarp: invalid cutline after RPC reprojection

Reported by: Even Rouault Owned by: Even Rouault
Priority: normal Milestone: 2.1.0

Description

When using gdalwarp with a RPC transform and a cutline, it may happen that the cutline once reprojected to source image pixel coordinates is no longer a valid geometry (self-intersection polygon) due to insufficient node density before reprojection.
