Image caching keeps the images opened. 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.
LV_IMG_CACHE_DEF_SIZE must be >= 1
