#3 Compilation error when using g++, vector types, BOUNDARY_CONSTANT, and scalar constat.

[Richard Membarth]

The following examples can be compiled by clang++ since the scalar '1' is automatically propagated to uchar4, however, this is not the case when compiling with g++:

BoundaryCondition<uchar4> BcInConst2(IN, size_x, size_y, BOUNDARY_CONSTANT, '1');</uchar4>

[Richard Membarth]

This works in recent g++ versions (tested 5.4.0 and 6.2.1).

New syntax:

BoundaryCondition<uchar4> bound(in, dom, Boundary::CONSTANT, '1');
