Memory use, performance, and Toit pixel display.

(March 2024).

Some applications using pixel displays may run out of memory, especially if you are running on a small ESP32 with no external PSRAM. This is especially the case if you are using the small jaguar server on the device for fast edit-compile-run development cycles.
