* Changes delegate property from assign to weak
In modern Objective-C delegate should be weak. In very rare conditions you might want delegate be strong.
Assign for delegate is sign of legacy code.
This change prevents crash when you forget nil delegate in dealloc and makes rush with nilling delegate unnecessary.
This change shouldn't break any existing code.
* Adds implementation for setters and getters for weak delegate properties for non ARC Obj-C files
For whatever reason compiler can't synthesize these.
And yes, it's time to convert all Objective-C stuff to ARC.
* seriously improved performance of blur function, especially 3x3 and 5x5 cases
* trying to fix warnings and test failures
* replaced #if 0 with #if IPP_DISABLE_BLOCK
- calculate ticksTotal instead of ticksMean
- local / global width is based on ticksTotal value
- added instrumentation for OpenCL program compilation
- added instrumentation for OpenCL kernel execution
