The algorithm is parallelized using a custom Mapper and Canvas class.
It is parallelized over the expected pixels that will be colored,
blending with any previous color value. This does not use the depth buffer
and hence will naively overrwite all pixels while drawing a line segment.

The RuntimeDeviceTracker.cxx contains a library method that queries the
CUDA device, which only works if compiled as a CUDA source file.
This set up will allow code that is not compiled with CUDA use a
RuntimeDeviceTracker with other code that does use CUDA.

There are many rendering classes that do not rely on OpenGL. We really
want to be able to use this functionality on systems that do not have
OpenGL. That is a big part of the point.
This reverts commit c75feb74bb6add43e1be9a42a9bf4bf205b97c39.
There is no code in the rendering library that uses GLFW. (GLFW is
currently only used directly by tests and examples.) This adds
unnecessary link dependencies that can only hurt us later.

If VTKm_ENABLE_OSMesa was on but OSMesa was not found, CMake would just
give a status update but happily configure. This change checks for the
condition where VTKm_ENABLE_OSMesa is on but OSMesa was not configured
correctly and raises an error in this case.
UnitTestMapperEGL.cxx: MapperGL is no longer a templated class.
UnitTestMapperGLFW.cxx: strmp needs cstring
rendering/CMakeLists.txt: need to append egl_sources to sources.
The clang compiler was running into linker errors constructors of
classes with virtual methods that were inline and destructors that were
not declared at all. In this case, the compiler was not creating
everything needed by a virtual table and the link died.
Also made the TextAnnotation classes conform better to VTK-m coding
style. Specifically, changed the order of words in subclass names (e.g.
TextAnnotationBillboard instead of BillboardTextAnnotation) and broke
out each subclass into its own header/source files.
When things in the rendering library need to execute things in parallel
(outside of another rendering library like OpenGL) it should run it on
available parallel devices. This means using TryExecute to attempt on
whatever devices may be available. It also means that some of the
sources must be compiled with CUDA's nvcc. To enable this, made a code
wrapping mechanism to compile within a .cu file.
I have noticed at least on my windows machine that source code that uses
the rendering package is taking a long time to compile. The rendering
library does not rely much on templates and more on virtual methods.
Thus, it is a good candidate for moving to a library so that it need be
compiled only once.
This sets up the configure scripts to create the library. There is also
a simple port of one class to the library. More will follow.
The VTKmConfigureComponents.cmake file has lots of careful configuration
of many of VTK-m components and dependent libraries (like OpenGL,
OSMesa, etc.) that takes care of several corner cases. The configuration
is consolidated here so that it can be consistent across the many
directories in VTK-m as well as other projects that use VTK-m.
Recent changes to the configuration in rendering circumvented these and
directly tried to configure dependent rendering libraries. This is wrong
(and more importantly broke my OSX build).
Have VTK-m eat its own dog food when it comes to its configuration. Load
the same configuration for building VTK-m as would be loaded (more or
less) when using find_package(VTKm) in an external project.
This includes adding lots more components to the packages so that all the
setup (e.g. OpenGL, TBB, etc.) can be set up correctly. It is also a
significant change to how these components are declared. The component
configuration is simplified a bit and unified in a single file.
Move some of the management of the width, height, and buffers to the base
Canvas class. Also, when it makes sense, get the width and height from
the rendering system.
Also changed the color buffer to be a Vec so that you don't have to
manage array offsets by hand.
All of these changes snowballed from the observation that the glut
example did not properly enable the depth buffer.
