Cast a capsule mover through the world. This is a special shape cast that handles sliding along other shapes while reducing clipping. This is not a good source of information about what the mover is touching. Instead use the planes returned by b3World_CollideMover. @param worldId World to cast the mover against @param origin World position the mover capsule is relative to @param mover Capsule mover, relative to the origin @param translation Desired mover translation @param filter Contains bit flags to filter unwanted shapes from the results @param fcn Optional callback for custom shape filtering @param context A user context that is passed along to the callback function @return the translation fraction
