misc... * restrict unwanted angle(s) keys commits on moving generic, eclassmodel, miscmodel entities * reverted angle(s), origin, scale entity keys save format from %f to %g * fix uniform rotation operations for generic entities with angles key * use more precise meth for rotating point entities with only angle rotated * snap tiny inaccuracies in angle(s) and origin point entities keys * workaround: don't discard empty group ents, having origin key * entity class convertion: prevent converting worldspawn; prevent converting point entity to empty group
