read_rle_rgbe
Written by Lawrence A. Taplin (taplin@cis.rit.edu)
Based loosely on the c-code RGBE implementation written by Bruce Walters
http://www.graphics.cornell.edu/~bjw/rgbe.html
function to read a run length encoded RGBE picture file and header. This does
not work if the image is not RLE!!!
Note to Psychtoolbox users: Please use the higher level HDRRead.m
routine for better generality in your code. This routine is used as
helper for HDRRead.
