-// 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). 
-//

- * multiple buffers in an attempt to avoid unnecessary copying of input data.
- *
- * (A simpler scheme is possible: It's much easier to use only a single
- * buffer; when fill_input_buffer() is called, move any unconsumed data
- * (beyond the current pointer/count) down to the beginning of this buffer and
- * then load new data into the remaining buffer space.  This approach requires

- *
- * 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
- * if the current call returns FALSE.  Data beyond this point must be
- * rescanned after resumption, so it must be preserved in case the decompressor
