fixed bug in gpu filter engine (incorrect buffer type) and in vector's saturate_cast.

Browse Source 
changed buffer type in linear filters to float.
added support of 1 channel image to linear filters.
added support of BORDER_REFLECT101, BORDER_REPLICATE and BORDER_CONSTANT border type to gpu linear filters.
minor fix in tests.
update comments in gpu.hpp.
