Browse source 
Original commit message from CVS:

* gst/gstbuffer.c: (gst_buffer_new_and_alloc):
some debugging
* gst/gstcaps.h:
whitespace fixes
* gst/gstpad.c: (gst_pad_activate_push), (gst_pad_alloc_buffer):
more debugging
* gst/gststructure.c: (gst_caps_structure_fixate_field_boolean):
* gst/gststructure.h:
add a fixate function for booleans; add a FIXME that these func
names should probably be gst_structure_fixate_*
