+- light: add flood-filling to fix black seams in detailwall.map when no -extra/-extra4 used
+- light: fix color->greyscale conversion to be compatible with MarkV and some QuakeWorld engines
+- light: don't mark sample points inside semi-transparent shadow casters as occluded.
+- qbsp: add "_external_map_scale" key for misc_external_map
+- qbsp: experimental func_illusionary_visblocker entity

+- bsputil: "--check" option logs world mins/maxs
+- bsputil, bspinfo: can now read Q2 BSP files
