Added resizing existing text

Browse Source 
Added a function called resizeText, which can be used on already existing text to make it bigger or smaller, and even has a boolean incase you want the text to keep its midpoint or not.

If oldX is the old position, that is the same for both sizes of text, e.g. oldX = 50
And oldWidth is the old width of the text, e.g. oldWidth = 100
And newWidth is the current width of the text, e.g. newWidth= 150
And the midpoint, is always the same, e.g. midpoint = oldX + oldWidth/2 = 50 + 100/2 = 100
and the newMidpoint, which is equal to midpoint, is newX + newWidth/2, then
newX = midpoint - newWidth/2 <=> newX = oldX + oldWidth/2 - newWidth/2, e.g., <=> newX = 50 + 100/2 - 150/2 <=> newX = 25
