Added new flag GIL_NONWORD_POINTER_ALIGNMENT_SUPPORTED to indicate whether dereferencing on non-word boundary is supported. Enabling this flag improves performance. Fixed two bugs related to non-byte-aligned images. The image alignment parameter is now specified in bytes, and has a default of 0, which means "packed" alignment. In particular, for non-byte-aligned images alignment of 0 means there are no padding bits at the ends of rows. Added the allocator as an optional parameter to image constructors and image recreate methods. ........ r41167 | grafik | 2007-11-16 20:11:49 -0800 (Fri, 16 Nov 2007) | 1 line Add "--out-xml=xyz.xml" option that dumps the output of all actions, and the test.jam information, to the given file.
