[osg-users] Limit rendering a texture up to a given pixel

Hello, I have a big image to be rendered (100k pixels each side), hence I am partitioning that image in Image Tiles. Each tile has 256 x 256 pixels. Each tile consists of a osg::Geometry quad, with a texture bound to it. I put all those tiles in an osg::Group. I use a fragment shader that is glo
