Lots of fun parameters.	However, discovered two problems:	  - Lack of a default constructor with no arguments leads to	    problems when allocating textures in arrays.   Tried to fix	    by providing default sizes in sh, but this leads to problems	    with trait wrappers.   Added 1D, 2D, 3D versions of trait	    wrappers as a temporary fix, but I don't like it.  Will have	    to revisit this part of the design.	  - There is a bug with the initialization of output attributes	    modified with read-write-modify (i.e. +=); they don't seem	    to be getting initialized to zero properly.   Of course this	    means a hidden temporary is introduced, probably IT is not	    being initialized properly.2004-03-25  Bryan Chan <b8chan@uwaterloo.ca>	* src/AlgebraShader.cpp: Added demo of algebra (note: this	  generates *lots* of subshaders, so it might be a good idea to	  disable it by default in Makefile.am)	 2004-03-18  Bryan Chan <b8chan@uwaterloo.ca>	* src/EdgeGooch.cpp: Added Gooch w sillhouette shader.	2004-03-15  Stefanus Du Toit  <sjdutoit@uwaterloo.ca>	* src/ShrikeFrame.cpp: Add a menu item to change the background colour.	* src/ShrikeCanvas.cpp (setBackground): Allow the background	colour to be changed.	* src/UniformPanel.cpp (setShader): Allow the user to change textures.2004-03-11  Bryan Chan  <b8chan@uwaterloo.ca>	* src/NoiseShader.cpp: Moved shdemo over to shrike.	2004-03-11  Stefanus Du Toit  <sjdutoit@uwaterloo.ca>	* src/ShrikeFrame.cpp (setShader): Use firstTimeInit() here	instead of initializing everything in initShaderList(). This cuts	down the startup time a lot.	* src/Shader.cpp (firstTimeInit): Implement firstTimeInit(), which	only calls init() once.	* src/Shader.hpp: Add a prototype for firstTimeInit().	* src/Textures.cpp: Added a simple example of using textures.	* src/Pants.cpp: Added this really cool new shader.
