• Changed collision mask 'layer-11' to 'rail-layer'.
• Changed collision mask 'layer-12' to 'transport-belt-layer'.

• Implemented NoiseExpressions::fromPropertyTree for the "offset-points" noise expression function.
• Removed rocket silo rocket prototype property "result_items" because it did nothing.
• Added draw_as_light and draw_as_glow property to sprite definitions. draw_as_shadow, draw_as_light and draw_as_glow are mutually exclusive and draw_as_shadow takes precedence.

• Added direction to SimpleEntityWithOwner and SimpleEntityWithForce.
• Constrained collision_box and collision_mask of transport belt connectable prototypes so it is not possible to build the entities in overlapping positions. (more)
• Added optional draw_fluid_icon_override boolean to pipe to ground prototypes. Causes fluid icon to be drawn, ignoring the usual pair requirement.

Scripting

• Renamed the clean_cursor method to clear_cursor.
• Renamed on_put_item to on_pre_build, as it is much more precise name for that event. It fires when anything is used for building: item, blueprint, blueprint record or ghost cursor.
