Fix a Python 2 problem with the hotkey manager having mixed Unicode and ASCII strings which was causing a conversion exception.

In the HDK, FS_WriterStream::myStream is now an UT_UniquePtr. Subclasses of it will need to be modified accordingly.

Various fixes for the animation graph editor

• Fixed a bug where ctrl-moving keys in multiple channels worked inconsistentlydepending on whether you selected the key's in-value or out-value.
• Fixed a bug where the tangent handles of the first key of a channel would visuallyappear in the incorrect location if its value was untied.
• New behaviour: If one side of a key has a manual slope and the other is automatic,its slopes will now always be untied. This prevents some edge cases where a keycan have different slope values even when its slopes are tied.

Fixed a bug where, under variance convergence mode, matte holdout objects would always cast maximum number of secondary rays allotted when there are no holdout AOVs present and take longer to render.

Added new HAPI functions for faster attribute transfer. Integrated into Unreal.

Optimized scene processing when there are no render-time procedurals present.

Fixed an issue where the Instancer LOP wouldn't always author time samples when the incoming target points were animated via time samples.

The maximum output field is now editable when modfying the type properties of a TOP asset.

Fixed a possible crash subdividing mesh with a degenerate face.

Fixed a bug in the Lattice SOP that could result in a crash when the second input is not connected.

Fixed an HQueue bug where a client sometimes got stuck in an endless loop of failing to send job status messages to the server. This resulted in thousands of client errors appearing in the HQueue website.

Fixed issues with promoting VOP input with MMB > Promote Input, which was not setting up a channel reference like voptoolutils.inserParmVop() did. Also fixed the undo blocks to clean up such channel references when undoing.

Use new input types instead of old input types on plugin load.

Fixed a bug in the MatchSize LOP which prevented it from working with second input geometry.

Fixed a bug where the arrow keys and non-symbolic keys were not working properly on OSX with Qt built to target version 10.15 or later.

Fixed SolveIK VOP rest angle computation from targets with more than 3 joints. We were accumulating rotations using a single quaternion when computing the rest angles and that would lose the rotation frame on the second rotation. This was preventing IK chains from staying static when configured.

Fix the current frame indicator when opening a new Animation Editor (Alt+Shift F) window. The current frame was keeping the default value of 1 until the next time change event.
