Basically, I have the ARCamera which shows the video feed. I have other cameras that have orthogonal projections that show images. When the user presses a button, I want to "copy" the last frame of video onto a texture that sits on a plane, and this plane must fill the phone's display (just like a GUITexture would). Except, I can't use a GUITexture because I need to draw over top of it. I can't use a WebCamTexture because it is well known that this doesn't work on MANY Android devices.
