+It currently supports PNG files which are stored progressively (most of them),
+including those with transparency. Since no scaling is applied to the output, it
+works best with images of size 256x212 or smaller. Beware that because it first
+decompresses the PNG fully before showing it, it can be very memory hungry.
+What remains before making an official release is to:
+  * Support PNG “interlaced” storage mode (to be fully spec compliant)
+  * Reduce memory requirement to 64K
+  * Support screen modes other than screen 8
+  * Scale large images (currently shows top left corner)
