* TBB executor for GAPI - the sole executor - unit tests for it - no usage in the GAPI at the momnet * TBB executor for GAPI - introduced new overload of execute to explicitly accept tbb::arena argument - added more basic tests - moved arena creation code into tests - * TBB executor for GAPI - fixed compie errors & warnings * TBB executor for GAPI - split all-in-one execute() function into logicaly independant parts * TBB executor for GAPI - used util::variant in in the tile_node * TBB executor for GAPI - moved copy_through_move to separate header - rearranged details staff in proper namespaces - moved all implementation into detail namespace * TBB executor for GAPI - fixed build error with TBB 4.4. - fixed build warnings * TBB executor for GAPI - aligned strings width - fixed spaces in expressions - fixed english grammar - minor improvements * TBB executor for GAPI - added more comments - minor improvements * TBB executor for GAPI - changed ITT_ prefix for macroses to GAPI_ITT * TBB executor for GAPI - no more "unused" warning for GAPI_DbgAssert - changed local assert macro to man onto GAPI_DbgAssert * TBB executor for GAPI - file renamings - changed local assert macro to man onto GAPI_DbgAsse * TBB executor for GAPI - test file renamed - add more comments * TBB executor for GAPI - minor clenups and cosmetic changes * TBB executor for GAPI - minor clenups and cosmetic changes * TBB executor for GAPI - changed spaces and curly braces alignment * TBB executor for GAPI - minor cleanups * TBB executor for GAPI - minor cleanups
