ENH: Add support to read tiled tiff images

vtkTIFFReader does not correctly read tiled tiff images.
Added a variety of tiled images and a test.
Added support for flipped volumes.

Fix Context2D to clear the current shader before drawing.

Context2D uses default shaders for some of its drawing. Minor
change to clear the cuyrrent shader back to a default one.

Fix lighting overdrive on ImagePlaneWidget

ImagePlaneWidget was setting Ambient to 1.0 but leaving diffuse
at 1.0 as well. This exposed a difference in the backends where
the old backend truncated to 1.0 then modulated by texture and
the new modulates by texture and then truncates to 1.0. Fixed by
explicitly setting diffuse to 0.0 which was the intended effect.

cmake: use COPYONLY rather than COPY_ONLY

Change-Id: I0e9a53fa64a91c90b4b0c60f96b873dd9acd76e2
vtkWrap: some uses of COPY_ONLY weren't even wrong

These instances are @ONLY, not meant to be COPYONLY which is what
COPY_ONLY might have indicated.

Camera was caching when shared between multiple renderers

Fix so that when a single camer ais shared between multiple renders
the cache resets when switching renderers. Fixes cubeAxes2 test.

Fix unnormalized interpolated normals

Interpolated normals are typically not unit length and need to
be renormalized in the fragment shader. This change adds
normalization for normals that are passed through the vertex shader
and therefore interpolated. This change replaces a number of valid images
that were previously added for OpenGL2 due to Phong lighting changes and
it adds a number of new images due to the phong lighting change that
are now showing up. Almost all the cases involve rendering low resolution
spheres and cylinders, both of which come with normals in VTK and for which
phong lighting can make a big difference.
