[vlc-devel] [PATCH] variables: correct minimum float value

[Victorien Le Couviour--Tuffet]

FLT_MIN is the minimum normalized positive floating-point value not the minimum
negative value a float can contain. This is very different.
This fixes the issue with the adjust's hue variable, which has a range of
[-180;180]. When the variable was set lower than 0, it was clipped back to
zero.
