GUI - Slider control

[historic_bruno]

Example: Such a control would help in various parts of the UI that need numeric values chosen along a scale.

Unique attributes:

• Current value of the slider (possibly re-use caption field like other controls, should be readable/writable)
• Orientation (horizontal or vertical)
• Minimum value of the slider (left or bottom)
• Maximum value of the slider (right or top)
• Width of the button in screen coordinates
• Background area sprite
• Draggable button sprite
• Sprites for disable/pressed states

Advanced version with markers/intervals:

• Interval to place the markers (auto?)
• Marker sprite and size

For horizontal slider, left-right arrow keys should move it, for vertical slider, up-down arrow keys should move it.
