This builds all skia tests by treating iOS tools as executable applications. A few warnings were fixed as well. Removed old trace draw code and remnants. Review URL: https://codereview.appspot.com/6597063 git-svn-id: http://skia.googlecode.com/svn/trunk@5776 2bbb7eff-a529-9590-31e7-b0007b416f81

*
|
|
* Given three directory names, expects to find identically-named files in
|
|
* each of the first two; the first are treated as a set of baseline,
|
|
* the second a set of variant images, and a diff image is written into the

* third directory for each pair.
|
|
* Creates an index.html in the current third directory to compare each

* Recursively descends directories, unless run with --norecurse.

|
|
* Returns zero exit code if all images match across baseDir and comparisonDir.
