CGContextDrawImage() is not defined in Chromium -- it part of Mac OS X's quartz 2D library:
http://developer.apple.com/documentation/GraphicsImaging/Reference/CGContext/Reference/reference.html#//apple_ref/c/func/CGContextDrawImage I imagine the reason you can't step into it with XCode, is that it has no source code to display. You should be able to step through the disassembly instead.
