Palette actions menu

The palette actions menu contains stuff that pertain to palette operations.

• Generate optimal palette with x amount of colors
  Allows you to generate a palette using what is on the tilemap (works with blocks just as well).
• Clear entire Palette
  Self explanatory. Will set all colors to black. If you change your mind depending on when you change your mind you can either press No or press CTRL+Z
• Pick nearest color algorithm
  Retro Graphics Toolkit supports three different nearest color algoritms. Try them all and see which looks best.
• RGB color to entry
  When in the tile editor you can use the RGB sliders to select a color and using this option will convert that color to the closest color that can be displayed on the current system and put that in the currently selected palette entry.
• Entry to RGB color
  Opposite of above. Will get the RGB values for the current palette entry and set that value to the RGB sliders.
