| screenToPanelSpaceFunction | The translation function. Set to null to revert to the default behavior. |
Sets the function that handles the transformation from screen space to panel space. For overlay panels, this function returns the input value.
If the panel's targetTexture is applied to 3D objects, use a function that raycasts
against MeshColliders in the Scene. The function can first check whether the GameObject that the ray hits
has a MeshRenderer with a shader that uses this panel's target texture. It can then return the transformed
RaycastHit.textureCoord in the texture's pixel space. Return a coordinate outside the panel to
skip incoming pointer events if the ray doesn't hit a valid target or location.
A non-zero z value should be returned when the element at the given screen coordinate contains
3-D transformations that make it overflow forward or backward out of the panel's surface.
This z value is used by pointer events when converting between panel position and local position.
