	* Made multiple changes by including header files and removing
	unneeded variables so that -Wall -pedantic will return no
	warnings.

	* xfb_byte.c: Line 303: corrected improper parameters passed
        to XSetWMProperties.  (Just removes a compiler warning...)

	* build_pyr.c, collapse_pyr.c, convolve.c, convolve.h,
        edges.c:  Replaced the convolution code with a newer version
        developed by Eero Simoncelli for the Matlab steerable pyramid
        tools.  In the convolution code, changed double images to
        float images, and modified the function calls in build_pyr.c and
        collapse_pyr.c accordingly.  This shoud not change image encoding
        at all.

	* unepwic.c, epwview.c: The number of bytes read from the file did
	not properly take into account that the subband bin sizes were
	sent at the last moment.   Therefore the decompression routine
        overestimated the number of bytes read.

	* prob_dist.c: Lookup tables have been statically set to size 512
        (I know, that's not the best idea...).  Anyway, if MAX_NUM_BITS is
	a value other than 9, there is a bug with indexing into these
        tables.  This required bug fixes in estimate_pdf() and
        get_prior_CDF().

	* prob_dist.c: there was a bug caused by having MAX_NUM_BITS be a
        value other than 9 in function get_estimation_fraction().  The
        shift based on MAX_NUM_BITS should have been inside of the array.
