The previous commit only solves the problem when using the default theme using factory settings. For previously saved themes, there could still be problems, as the alpha values were still 0. This commit improves the logic here so that while keyframe points on unselected F-Curves will still get faded out (to not stick out too much from the curves they live on), but the effect will not be as pronounced (i.e. the points will stay visible all the time).
