### DemoDirectionalBlur01
[source code](src/jvmDemo/kotlin/DemoDirectionalBlur01.kt)
Demonstrates how to use [DirectionalBlur] by creating a `direction`
ColorBuffer in which the red and green components of the pixels point
in various directions where to sample pixels from. All the pixel colors
of the ColorBuffer are set one by one using two for loops.
Note the FLOAT32 color type of the buffer to allow for negative values,
so sampling can happen from every direction.
Every 60 animation frames the `centerWindow` property is toggled
between true and false to demonstrate how the result changes.

### DemoDirectionalDisplace01
[source code](src/jvmDemo/kotlin/DemoDirectionalDisplace01.kt)
[source code](src/jvmDemo/kotlin/DemoDirectionalBlur01.kt)
### DemoDirectionalDisplace01
Demonstrate how to use [DirectionalDisplace].
The direction map is populated using `drawImage` instead of
pixel by pixel. A grid of circles is drawn, each circle with a
color based on simplex noise. The R and G channels of the colors
control the direction of the sampling. By animating the sampling
distance the result oscillates between no-effect and a noticeable one.

[source code](src/jvmDemo/kotlin/DemoDirectionalDisplace01.kt)
### DemoDirectionalDisplace02
Demonstrate how to use [DirectionalDisplace].
The program draws 12 overlapping translucent circles on the
`direction` color buffer to produce new color combinations
on the overlapping areas. Those colors specify where the
`DirectionalDisplace` effect will sample pixels from.

### DemoOkLab01

[source code](src/jvmDemo/kotlin/DemoFluidDistort01.kt)
### DemoOkLab01
This demonstrates converting a [ColorBuffer] from and to (OK)LAB color space using the [RgbToOkLab] and [OkLabToRgb]
filters. The (OK)Lab representation is signed and requires a floating point representation.
