**Tags:** `2d`

Generates a test panel texture with distinct corners, edges, and centre,
then renders NinePatchRect nodes at various sizes to demonstrate that:
  - Corners maintain their original pixel size
  - Edges stretch in one direction only
  - Centre fills the remaining space

Shows the engine's in-memory texture API: the ``texture`` property on
NinePatchRect accepts an RGBA uint8 ``numpy.ndarray`` directly, no file
I/O required.
