+// The icon decoder is a decoder specifically tailored for loading icons 
+// from the OS. We've defined our own little format to represent these icons
+// and this decoder takes that format and converts it into 24-bit RGB with alpha channel
+// support. It was modeled a bit off the PPM decoder.
+//
+// Assumptions about the decoder:
+// (1) We receive ALL of the data from the icon channel in one OnDataAvailable call. We don't
+//     support multiple ODA calls yet.
+// (2) the format of the incoming data is as follows:
+//     The first two bytes contain the width and the height of the icon. 
+//     Followed by 3 bytes per pixel for the color bitmap row after row. (for heigh * width * 3 bytes)
+//     Followed by bit mask data (used for transparency on the alpha channel).

+ *
+ * (A simpler scheme is possible: It's much easier to use only a single

+ *
+ * At any one time, the JPEG decompressor is either reading from the necko
+ * input buffer, which is volatile across top-level calls to the IJG library,
+ * or the "backtrack" buffer.  The backtrack buffer contains the remaining
+ * unconsumed data from the necko buffer after parsing was suspended due
+ * to insufficient data in some previous call to the IJG library.
+ *
+ * When suspending, the decompressor will back up to a convenient restart
+ * point (typically the start of the current MCU). The variables
+ * next_input_byte & bytes_in_buffer indicate where the restart point will be
