Prepend a value node on all (non-constant) node inputs without a link.

In principle the input value could be used directly in codegen, but this
approach means one less condition to check and has the same effect.

Fix for incorrect output type displace element.index.

Added a simple operator and panel for one-click debug display of bvm node visualizations.

This was formerly part of an addon, but is useful enough to include directly in the branch
for debugging purposes. It uses the existing graphviz dump functions to write into a
temp dot file, then runs graphviz on it and opens the resulting image in the standard
system image viewer.

This is tailored for linux systems, but that shouldn't be a big issue since most developers
(who are the target audience) use this platform anyway.

Use the new node block structure in code generation, to determine dependencies of symbols.

More elegant construction of implicit node blocks, by copying argument node first.

Decklink test build

Merge remote-tracking branch 'origin/master' into experimental-build

VideoDecklink: fix compilation warning in Windows.

VideoDecklink: accept mode index, test dvp.dll presence, enable audio just in case.

mode index instead of mode name can be used when opening the card:
VideoDecklink("1/2vuy",0)
The list of video mode is specific to each board and this method is
therefore not generic. Only use it for debugging purposes.

VideoDecklink will not throw if dvp.dll is not found when opening a Decklink
card on Windows with a nVideo Quadro GPU; instead it will fallback on
standard OpenGL transfer. It is preferable to use dvp.dll when possible as it
provides faster image transfer to Quadro GPU.

Audio Input is now enable by default with 48KHz sampling, 16bit samples and
2 channels. This is normally not necessary because audio is not used in
VideoTexture; it is just in case it is necessary on certain Decklink card.

Fix compile error.

wavelet fixes and refactored smoke.h

Represent nested node blocks in the graphviz debug dump.

Cleanup: class for debug dumping functions for node graphs.

Moved the block definition from codegen to the node graph optimization.

This now involves making actual copies of nodes, so that each block has
a unique instance of each node and ambiguity is avoided.
