RiveTexture.cs mouse interaction does not work with 2D canvas and 3d objects

[BitBarrel]

There are several issues with hit testing in RiveTexture.cs:

-Mouse interaction (both mouse up, mouse down, and mouse move) does not work if a Rive texture is applied to a 3D object.

-Similar to the point above, mouse interaction does not work with a 2D canvas image component or a RawImage component.

-If Y is flipped due to DX11, hit testing is not correctly translated for both a regular material and a RawImage or Image component.

-If a riv file are applied to different objects, the riv animations are all copies instead of individual instances. So if you click on one item, all the other items also display the same click animation.
