// Technical notes
// ===============
// If an effect name is followed by an @, slider and color control is effective.
// See setSliderAndColorControl in index.js for implementation
// If not effective then:
// - For AC effects (id<128) 2 sliders and 3 colors and the palette will be shown
// - For SR effects (id>128) 5 sliders and 3 colors and the palette will be shown
// If effective (@)
// - a ; seperates slider controls (left) from color controls (middle) and palette control (right)
// - if left, middle or right is empty no controls are shown
// - a , seperates slider controls (max 5) or color controls (max 3). Palette has only one value
// - a ! means that the default is used.
// - For sliders: Effect speeds, Effect intensity, Custom 1, Custom 2, Custom 3
// - For colors: Fx color, Background color, Custom
// - For palette: prompt for color palette OR palette ID if numeric (will hide palette selection)
//
// Note: If palette is on and no colors are specified 1,2 and 3 is shown in each color circle.
// If a color is specified, the 1,2 or 3 is replaced by that specification.
// Note: Effects can override default pattern behaviour
// - FadeToBlack can override the background setting
// - Defining SEGCOL(<i>) can override a specific palette using these values (e.g. Color Gradient)
