Description
Currently, if you have multiple overlapping source tiles (e.g. reprojected data) with gdal_retile.py, each tile written overwrites the data in the destination region.
The attached patch adds alpha compositing for RGBA images to gdal_retile.py.
If source images have an alpha channel, they are composited on top of the destination region using Porter Duff src-over compositing.
The behavior for images without an alpha channel is unchanged.
This means gdal_retile.py now requires numpy.
