					 y_td - Styles for text draws!
					===============================
Description:
	Provides a wrapper to the SA:MP text_draw functions offering much
	improved functionality including XML definable styles, safe display,
	timed displays, styles and text separated, styles updateable dynamically
	and more.

	Tells the system to remove a text draw when no-one can see it
	anymore to free up text draw slots.
	
	Note that linked TDs don't share garbage status.  This is because I said so,
	not for any good reason (other that I can't be bothered to code it up).
	Ergo this behaviour is a feature, not a bug!

Function:
	TD_Morph
Params:
	Text:textDraw - Text to morph from it's current style to another style.
	Style:style - The style to morph to.
	time - The time to take in this morph.
	defer - In how long to start this morph (default now).
Return:
	-
Notes:
	Entry point for changing the apperance of a text draw to look like another
	one.  How smooth this is depends on the difference and the time given.  The
	default update time is 50ms (20fps), which isn't too bad.  Don't modify
	revision versions in here as if there is a hide timer, it still applies
	regardless of what style is currently applied.
	
	No longer takes a playerid parameter - it's just tough but easy to work
	around using y_text.
