If only the built-in image formats are used there is no real advantage of caching.
(I.e. no new image decoder is added).
With complex image decoders (e.g. PNG or JPG) caching can
save the continuous open/decode of images.
However the opened images might consume additional RAM.

When LVGL calculates the gradient "maps" it can save them into a cache to avoid calculating them again.
LV_GRAD_CACHE_DEF_SIZE sets the size of this cache in bytes.
If the cache is too small the map will be allocated only while it's required for the drawing.
0 mean no caching.

Error diffusion dithering gets a much better visual result, but implies more CPU consumption and memory when drawing.

routines for PXP (lv_gpu_nxp_pxp_osa.c) and call
lv_gpu_nxp_pxp_init() automatically during lv_init().
Note that symbol SDK_OS_FREE_RTOS has to be defined in order
to use FreeRTOS OSA, otherwise bare-metal implementation is
selected.

lv_init().
