;=====================================================================================
; tBubble() - Thought Bubble function for displaying the thoughts of players
; and NPC's. Could also be used to make cheesy cartoon clouds,
; puffs of smoke, or whatever else comes to mind.
;=====================================================================================
;Parameters:
; ex,ey are the center coords of the main ellipse used to construct the thought bubble
;
; ew is the total width of the main ellipse ( xRadius * 2)
; eh is the total height of the main ellipse ( yRadius * 2)
;
; bump is a value used to determine overall height of bumps encircling the main
; ellipse - inversely proportional (i.e. smaller bump values make bigger bumps
; and larger bump values make smaller bumps)
;
; pen determines the width of the outline stroke used to draw thought bubble
;
; outline is a hex color value of bubble outline (default = black)
;
; fill is the hex color value used to fill the bubble (default = white)
;
; (NB: pre-defined constants recommended for hex color values or use rgb2hex function)
