Tilemap.library bounty

Step 1:  Convert ScrollingTrick sources to shared library.
Step 2:  Add BOB/VSprite support with multi-region clipping.  (This is NOT optional because the ScrollingTrick algorithm introduces a Copper seam that allows wrap around from the bottom to the top of the screen buffer to save Chip RAM.)
Step 3:  switch Copper handler to allow rainbows
Step 4:  make Amos extension as frontend and create simple examples
Step 5:  AGA version of the same
Stretch goal 1:  add TOME features like animated tile support and multi-tile Briks, then update the extension and make example AMOS codes to demonstrate the capabilities
Stretch goal 2:  CPU blitting for Fast RAM tile access and faster BOBs on 68020+ while possibly adding PowerBobs extension compatibility
Stretch goal 3:  Adapt to allow tiled dual playfield support
Stretch goal 4:  sidebar “screen” support using sprite hardware
Stretch goal 5:  Mesa version for AROS graphics card users
Stretch goal 6:  MiniGL/TinyGL version for NextGen Amiga-like systems without requiring an emulator
Stretch goal 7:  OpenGL/latest Mesa version for Mac/Linux/Windows systems (depends on stretch goal 5 or 6 being met successfully).
