2593	GUI - Slider control	historic_bruno		"Example: [[Image(wxwidgets-slider.png​)]]
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
* Slider for integer or float values

Advanced version with markers/intervals:
* Automatic placement of markers in equal intervals
* Custom placement of markers, labels and tooltips on mouseover
* Marker sprite and size


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