Committed by: keithp

Update of /cvs/cairo/cairo/src

	* src/cairo-pattern.c: (_cairo_pattern_shader_init):
	Initialize op->stops[0].scale = 0.  
	
	This scale value is used only when computing gradient values
	before the defined range, in which case stop 0 is used for both
	ends of the interpolation, making the value of 'scale' not
	actually matter, except that valgrind notices we're using
	an undefined value.
