Updated Transform, added Decompose and minor changes Updated Transform so it accepts a greyscale input per parameter. For each pixel, the parameter is multiplied by 2*v-1 (v being the value of the input's pixel) which makes it possible to affect the strength of each transform using an input image. New effects such as whirl and color guided offsets are now possible. Added Decompose node (does the opposite of combine). Used another color for inputs/outputs that expect/generate a greyscale image.

Node editor updates and support for alpha channel Added initial support for alpha channel (in combine, decompose and blend nodes). Textures with alpha channels can be exported using the material node albedo input. Updated node editor with a simple editor for enumerated parameters.
