slider issue

[reaperpaster]

i noticed that the slider max_value works perfectly but the min value is always 0 same changing it

[rcszephyr]

On key down function:

value = min_value + (max_value - min_value) * (cursor.x - ix) / position;

On slider render (width):

(value - min_value) / (max_value - min_value) * position
