015943d78f Use pthread_once() to guard the initialization of sPaletteConverter. This 
changes the semantics slightly: Previously after a failed initialization
another invocation of InitializeDefault() could theoretically initialize the
converter. Since the only error conditions are out of memory and broken app
server connection, this shouldn't really matter, though.

f6e4cbb952 * Rewrote BeBuild.h which had "a few" consequences (got rid of all those class 
definitions).
* Minor cleanup here and there.

65e63b987d PaletteConverter now exports a static InitializeDefault() method, which 
can be used (and is, by _init_interface_kit()) to initialize the ... 
er... default instance of 
PaletteConverter using the system color map, thus avoid building the 
list of colors, which takes some time. Fixes bug #505.

bdc6f9e7ef * Fixed a swapping bug for 16 bit colorspaces 
* Added some comments
* Added some checking to avoid noop shifts
* Added buffer length checks
* Implemented (as Stephan suggested) a version of ConvertBits() that takes offsets.
This new version allows to move a region of the source into a region (possibly not at the same point) on the dest while converting colorspaces on the fly.

b09e53fae0 Wrote a new color conversion engine. It's 2-5 times faster than the old one (depending on colorspaces) and about half in size. 
I've put it into ColorConversion.cpp and moved PaletteConverter there too, cleaning up Bitmap.cpp.
