Reviewer's Guide by SourceryThis pull request adds two new classes, ColorBand and SaturationBrightness, to implement color selection functionality in the TLStudio widgets. The changes focus on creating visual representations of color components using SWT (Standard Widget Toolkit) and custom canvas implementations.

Hey @unknowIfGuestInDream - I've reviewed your changes - here's some feedback:
Overall Comments:
- Consider extracting common code between ColorBand and SaturationBrightness into a shared base class or utility methods to improve code reuse and maintainability.
- Replace magic numbers (e.g., 360, 24) with named constants to enhance readability and make the code more self-documenting.
Here's what I looked at during the review

suggestion (performance): Consider reusing GC and Image objects for better performance
Creating and disposing of Image objects on each paint event can be expensive. Consider caching and reusing these objects, only recreating them when necessary (e.g., on resize).
private Image saturationImage;
// In the constructor or initialization method:
saturationImage = new Image(this.getDisplay(), saturationBrightnessData);
// In the paint method:
if (saturationImage == null || saturationImage.isDisposed()) {
saturationImage = new Image(this.getDisplay(), saturationBrightnessData);
}
gc.drawImage(saturationImage, 0, 0);
// In a dispose method:
if (saturationImage != null && !saturationImage.isDisposed()) {
saturationImage.dispose();
}
