+// 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
+ * decides to backtrack.
+ *

-# Revision notes:
-#
-# In the IRIX compilers prior to version 7.2, -n32 implied -mips3.
-# Beginning in the 7.2 compilers, -n32 implies -mips4 when the compiler
-# is running on a system with a mips4 CPU (e.g. R8K, R10K).
-# We want our code to explicitly be mips3 code, so we now explicitly
-# set -mips3 whenever we set -n32.
