### Sine ### Pattern
This generator creates sine wave based vertical bars. This generator creates a greyscale image by mixing an horizontal and a vertical pattern.
It will soon be replaced with a more flexible generator (similar to the PatternFunction in NeoTextureEdit) Patterns can either be based on a sine, triangle or square waveform (i.e. the color as function of the x or y coordinate).
The frequency (number of waves per unit) be configure for both axes.
Its parameters are the number of bars and a multiplier applied to the sine wave (higher values will make the bars sharper). Mix functions can also be configured.

* the bevel at the edge of the bricks * the bevel at the edge of the bricks
The bricks generator has 2 output:
* the first one will show mortal as black and bricks as white (bevel being shown as a gradient). It can be used as mask to mix brick and mortar, or to generate depth and normal textures
* the second one will just show a different color for each brick. It can be used to affect the brick's colors (and will be used in the future to offset textures).

The Voronoi generator has 3 outputs:

* The second output shows a greyscale image where intensity depends on the distance to the cell edges
* The third output shows a different color for each cell.
