Returns the maximum number of colors supported in a custom image cursor palette.
Note: if an image is used which has more colors in its palette than the supported maximum, the implementation will attempt to flatten the palette to the maximum. This may result in a loss of quality.
Note: These values can vary between operating systems, graphics cards and screen resolution, but at the time of this writing, a sample Windows Vista machine returned 256, a sample Mac machine returned Integer.MAX_VALUE, indicating support for full color cursors, and a sample Linux machine returned 2. Applications may want to target these three color depths for an optimal cursor on each platform.
