Two image widgets are created on the active screen. The left one binds
to the `img_png_demo` descriptor declared with `LV_IMAGE_DECLARE`, and
the right one reads `A:lvgl/examples/libs/libpng/png_demo.png` through
the filesystem driver registered under drive letter `A`. Both routes
go through the libpng image decoder.
