Version Notes for Houdini2.5

This document covers some of the changes which may be required to convert code written for Houdini2.0 to operate correctly with Houdini2.5.

Changes
Image I/O The old FB library has finally been replaced with a C++ library for image I/O. This is the IMG library. This library is extensible through the DSO mechanism, making it possible to add image formats/devices directly to Houdini (without the use of the FBio table).
UT_Raster/UT_TextureMap These classes have been moved to the IMG library. Any custom COPs will have to have the "UT_" replaced with "IMG_". The interface to the classes is basically the same. However, UT_RGBA and other pixel classes have been moved into UT_Pixel.h.
POPs It is now possible to add custom POPs (Particle Operators) to Houdini.
CHOPs It is now possible to add custom CHOPs (Channel Operators) to Houdini.
proto_install There is now documentation to help create archive files which can be extracted using proto_install.
Metaball kernel extensions It is now possible to add new kernel functions to the metaball library using a DSO mechanism.
