For `lv_span_set_text(span, "big");` How to differentiate between static (`lv_span_set_text_static`) and dynamic text (`lv_span_set_text`)? or deprecate the static interface ?

To improve performance, should we cache the width and height for each span ? For now, only spangroup have cache for width and height.

For ETC2 encoder & decoder, we can reference to https://github.com/Ericsson/ETCPACK

OK. I‘ll open a issue to discuss it.

The reason for this issue may be that the `stride` in `struct lcddev_area_s` has not been initialized. @halyssonJr can you help to add `memset(lcddev_obj, 0, sizeof(struct lcddev_obj_s))` after the code...

Having a [screenshot](https://github.com/lvgl/lvgl/blob/master/tests/README.md#asserts) for a transformed layer and an assert for the [memory leak](https://github.com/lvgl/lvgl/blob/master/tests/src/test_cases/cache/test_cache.c#L131-L138) would be great. OK....
