Canvas questions

[ams-hh]

Good morning,
I'd like to start with canvas/sprites and read and test the SpriteGif example.
Here is my first questions about this subject:

(1)
In all examples I can find, the canvas is made the same size as the display.
(First two Parameter of: Arduino_Canvas(int16_t w, int16_t h, Arduino_G *output, int16_t output_x = 0, int16_t output_y = 0, uint8_t rotation = 0);)
So the contents of the canvas is then transfered to the display by flush() to the position 0,0 as a 1:1 copy. Right?

What I'd like to achieve is a smaller graphic, which is created in the canvas and then punch it to several positions on the display. So I call the constructor with Arduino_Canvas(50, 80, myGFX, myPosX, myPosY, myRotation);

But as far as I could see is that the Output-Pos and Rotation is fix. I did not find a method to change them so that with flush() the canvas is always punched to the same position/rotation.
Or did I missed something. If yes, please give me hint!

[What I was lookin for is something like flush(X, Y)]

(2)
Is it possible to MOVE an existing canvas, that is seen on the Display? (Sprite-Function!) All I can see this moment is to clear the old punch on the screen and then flush the canvas again (if possible to different position. See (1)).

Thank you
