#64 Workspace limit sometimes is very big

[evalle]

Enabling the workspace limit in the program is usefull to not reach window borders and end up resizing things when wanting just to click something near the border. The value to apply to each border of the screen (top, bottom, left and right) is implemented as an integer value that represents a percentage of the screen. In some situations this space can end up being bigger than someone would want (I notice that in wide screens) preventing from using scrollbars or to select something near the border of the active window. I think that those percentages should be implemented as floats instead of integers to allow lower limits be defined.
