[3rd attempt] fixed HOGDescriptor::detectMultiScale() to group weights as well as ROIs
Reverted back to the previous method where a public method groupRectangles was added to HOGDescriptor to take care of ROI and weight grouping
Added spacing in a nested template argument list.
added documentation for OpenGL interoperability
Fixed bug #3101, problem on ellipse2poly function
Added brackets around line 888-892 for correct code!
adding/tuning multiple run for perf tests failing due to big deviation (functions using TBB can work so)
fixing warning on shadowing local var (TEST_CYCLE_MULTIRUN uses 'r')
Added all *.cpp samples reference to the 2.4.6 documentation as discussed in feature #3169
- Used lunix style slashes - works on most systems
- Removed all trailing whitespaces
