Update clip-path-shape-003.html and clip-path-shape-004.html because 1. Per SVG2 spec, we don't accept comma among commands, so I remove them. 2. Basically, these two tests want to test the result of `shape()` should be identical to the result of `path()`. However, I noticed the original tests which put a `clip-path:path()` with `position:absolutely` may have a fuzzy result if the path has some curves there. This may be caused by anti-alias together with absoultely positioned element (note: perhaps there are some floating point calculation in layout for this, so the final rendering coordinates may have some fractions). Therefore, I drop the absolutely positioned element, and just test that if the result of `shape()` is identical to the result of `path()`. Also, add two more tests for different reference-boxes together with the usage of `shape()` (to make sure we resolve percentage values properly).
