GUI decimal place control for size properties

Idea created by 1_Lortorial on Dec 13, 2010

    All the graphical user interfaces controls that deal with 'size' properties should have the ability to work in decimal places. Ideally two decimal places. For example the current halo dialog box displays decimal places for the halo size, but the size controls only works in whole numbers. To set the size property to decimal precision a user must type the decimal places into the dialog box. This process is slow and inefficient.

    Dialogs that would benefit from GUI decimal control include, but are not limited to:

    * Font Size
    * Marker Size (including outline width)
    * Halo Size
