ENH: add reset function to resource probe

Change-Id: Ife65fdcdcce6b097cc6b0064e41e7c3792c10eaa
STYLE: Save deference iterator mapped type to variable

Saving results of require computation is good practice.

Change-Id: I31c3083c8d4e362f2be8faff54ad817687557fa6
PERF: switch to scanline and linear iterators

Use scanline iterator and only report progress after a line is
processed.

BUG: Increase tolerance for itkFEMC0TriangularElement-NodalLoads-BCs

On builds with the -m32 float, different numerical results are obtained
without -ffloat-store (due to differences in floating point precision during
the computation).

COMP: Add missing call to cmake_minimum_required

The VXL_PIC_COMPATIBLE check CMakeLists.txt file recently started using
the cmake_policy() command.  This command is advanced enough to trigger
the CMP0000 requirement for cmake_minimum_required to be called.  Add
the missing call.

COMP: Fix checks for system libtiff

The wrong cmake include path variable was used.

CMake's check_symbol_exits requires the result to be fully linked,
which is difficult for libtiff due to possible additional
dependencies on zlib and jpeg. By using check_type_size on the
function name (a pointer), the linking dependency is removed.
The symbol exists in tiff 4.0.3, and requires library.
