[gdal-dev] gdal rasterize vs resize

[Scott]

Hey Jukka,

Yes, the behavior has existed for quite some time on the utilities. If 
you know the extent it's easy to calculate the -tr, (max - min) / pixels.

Being that the functionality exists elsewhere and given the fact that 
I'm LAZY, it would be nice to have everywhere. :)

Thanks!
Scott
