bugle-stats_fragments — gather fragment counts
filterset stats_fragments
The stats_fragments
filter-set provides
signals for the number of fragments to other filter-sets. It must
be listed in a chain that uses any statistics related to fragment
counts.
It is simply a wrapper around GL_ARB_occlusion_query, so a fragment is defined exactly as in that extension (and OpenGL 1.5), and will not work unless that extension is supported.
