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.
Updated library code to be able to store a group of nodes.
Added keyboard shortcuts:
- Del to delete selected nodes
- C to center the view
Modified paste action to paste at the center of the view.
New example (biohazard from webbzeug)
- Added a combine node that assembles channels into colors
- Added an emboss node
- Added an export node that generates additional file when exporting the material
- Refactored convolution related code
* updated transform node (scale split into scale_x and scale_y, and added a repeat parameter)
* added blend modes (burn, dodge, lighten and darken)
* added a (very bad) blur node, based on generic convolution code
* rewrote normal_map node using convolution code
