Description

Return true if the default camera implementation should query the current projection matrix at the start of the render frame and apply late update. In order to support late update, the plugin should refresh the current projection matrix just before rendering starts. A good point to insert the update is in OnBeginRendering_GameThread or OnBeginRendering_RenderThread.

Note that late projection update isn't compatible with all XR implementations because of projection matrix fetch restrictions.
