GYP changes and scripts for compiling Skia for ChromeOS

gyp/chromeos_deps.gyp

+# This GYP file stores the dependencies necessary to build Skia on the Chrome OS
 # platform. The OS doesn't provide many stable libraries as part of the
 # distribution so we have to build a few of them ourselves.
-#
-# We tried adding this gyp file to the android directory at the root of
-# the Skia repo, but that resulted in the generated makefiles being created
-# outside of the intended output directory. So to avoid this we created a simple
-# shim here that includes the android_deps.gypi file.  The actual dependencies
-# are defined and maintained in that gypi file.
-#
-# Also this assumes that the android directory is a sibling to the directory
-# that contains your primary Skia checkout. If it is not then you must manually
-# edit the includes below to specify the actual location of the android.gypi.
-# This is due to the fact that we cannot use variables in an includes as the
-# variable expansion step for gyp happens after the includes are processed.
