This blends two "565"-format bitmaps, including byteswapped ones. All the bitmaps have to have the same memory format. The routine takes about 63ms on a Kaluga when operating on 320x240 bitmaps. Of course, displaying the bitmap also takes time. There's untested code for the L8 (8-bit greyscale) case. This can be enabled once gifio is merged.

It doesn't fit on pybadge or pygamer. |
.. this needs to imply the disabling of RGBMATRIX too

The PR has been updated to include "L8" (greyscale) blending, & several boards that are unlikely to need it have had framebufferio disabled in order for this to fit. |

The demo below is real-time. It's using directio (
display_bus.send(44, bitmap)) to send bitmap data to avoid displayio overhead.PXL_20211104_213146186.mp4.2.mp4
