Added variance anti-aliasing to direct area light sources under Variance convergence mode.

Added new signature to primarclen vex functions that takes an int input.

Increased the default value of the Distance-based Packed Geometry Culling limit to account for improvements in GPUs since this feature was implemented in 16.5.

The Pyro Trail Path's distribution guide now works.

Pyro Scatter from Burst has a default speed of 24 m/s, rather than $FPS m/s. The velocity scale of this and the Pyro Trail Path are now based around 1m/s rather than $FPS m/s

Fixed a viewport distance-based packed prim culling bug when the packed prim had multiple materials assigned to it (instances were not being culled). This was most noticable when using LOPs.

Fix bug with Attribute Adjust Vector where it was rebuilding the VEX code for any input changes, introduced in 18.5.330.

Adjusting direction and length independently will now be allowed even if the attribute is only set by default values.

The Sublayer LOP sets its "last modified primitives" values to be all the root prims of the output stage. This means a Sublayer LOP followed by a default Transform LOP will transform the whole scene instead of nothing.

The Assign Material LOP button to select a Material primitive now always brings up a primitive chooser dialog instead of starting a viewport selection.
