Added initial support for texture operations

Import missing files

Save animated output result nodes within the graph

wrong file format saved

export animated images as an image strip or as a single image

Changed offset to use a normalized value rather than pixels

Implemented Transform offset X,Y

Animation render preview. Fixed a bug on closing.

Added first part of the Transform node, supports flips and 90 degree rotations.

animated texture output: final output now supports a list (even though it just uses the first one)

minor cleanup

Small refactoring to cleanup the syntax when trying to get a connected atom.

Code splitting to clean up that monolithic visualgraph.cs

Fix node being reprocessed if connected only through the output

Fixed crash when input sockets value was greater than the specified max
