So due to elements being painted onto a canvas i need to offer the user the ability to change the font size (different resolutions etc).
are there any opinions on regarding the pros on cons of the different font size controls.
1.A jquery slider smaller -------------|-------------larger
- or say a number box with font size and a set button. Font size  (SET)
or the microsoft word style of a drop down list of font size. -10 -13 -22 -48
or a box that displays the font size with up and down arrows font size (up arrow) (down arrow)
