Takes a snapshot of the whole of this Render Texture.
The snapshot is taken immediately, but the results are returned via the given callback.
To capture a portion of this Render Texture see the snapshotArea
method.
To capture just a specific pixel, see the snapshotPixel
method.
Snapshots work by using the WebGL readPixels
feature to grab every pixel from the frame buffer
into an ArrayBufferView. It then parses this, copying the contents to a temporary Canvas and finally
creating an Image object from it, which is the image returned to the callback provided.
All in all, this is a computationally expensive and blocking process, which gets more expensive the larger the resolution this Render Texture has, so please be careful how you employ this in your game.
