The patch renames the existing functions (GetBounds(), GetClientBounds(), etc) by adding an |Untyped| suffix. It then adds typed equivalents, and uses those typed equivalents in all the call sites where it's easy to do so. The trickier remaining call sites are converted to use the Untyped-suffix version.
