The following changes were made by this CL: 1. Make flatten() a protected method as callers should use SkFlattenableWriteBuffer to flatten an object 2. Make flatten a const method (including subclasses) 3. Mark subclass implementation of flatten with SK_OVERRIDE 4. Ensure overridden flatten impls call their parent 5. Remove no-op implementations of flatten from subclasses Additionally, if necessary the unflattening constructor was also moved to the protected section of the subclasses header if it was not already there. git-svn-id: http://skia.googlecode.com/svn/trunk@3540 2bbb7eff-a529-9590-31e7-b0007b416f81
