Godot 3.5.1 with UV Shadows

Godot 3.5.1 customized with user-computed camera matrix.

Change camera type to "custom" to set individual components of the matrix. Couldn't find a Vector4 exposed in the editor so used a Vector3 for xyz and w rows in the matrix, plus an additional Vector3 for column w.  The mat[3][3] value is set to zero.
