Hi guys,

just started working with QGIS. Found a small bug in the example scripts. Not sure where to submit it.

In line 113 of Extract_raster_values_to_shapefile.py and line 85 of Extract_raster_values_to_CSV.py:
" if rX > rasterXSize or rY > rasterYSize:"
should be replaced by:
" if rX >= rasterXSize or rY >= rasterYSize:"

otherwise the script crashes when we get data from the raster at a point at the boundary of the raster (e.g. if the raster is 200x200pix we can get values for 0-199 and 200 should be caught as exception).

good work, love qgis already. At the moment trying to build a little lidar plugin.
