Subject: [E-devel]  [Patch][elm_map] Mouse wheel bug fix

There is mouse wheel bug. Actually I have made it in previous patch :p

When using mouse wheel, tile size was changed between 0.5 ~ 2.0 before
zoom level is changed. But actually it should be changed between
1.0 ~ 2.0. I have fixed it. If tile size is below 1.0,  it does zoom-out.
And if tile size is above 2.0, it does zoom-in.
