/*
SuperGif
Example usage:
<img src="./example1_preview.gif" rel:animated_src="./example1.gif" width="360" height="360" rel:auto_play="1" />
<script type="text/javascript">$$('img').each(function (img_tag){
if(/.*\.gif/.test(img_tag.src)){
var rub=new SuperGif({ gif: img_tag });
rub.load();
}});</script>
Image tag attributes:
rel:animated_src -	If this url is specified, it's loaded into the player instead of src.
This allows a preview frame to be shown until animated gif data is streamed into the canvas
rel:auto_play -		Defaults to 1 if not specified. If set to zero, a call to the play() method is needed
Constructor options args
gif 				Required. The DOM element of an img tag.
loop_mode			Optional. Setting this to false will force disable looping of the gif.
auto_play 			Optional. Same as the rel:auto_play attribute above, this arg overrides the img tag info.
max_width			Optional. Scale images over max_width down to max_width. Helpful with mobile.
on_end				Optional. Add a callback for when the gif reaches the end of a single loop (one iteration). The first argument passed will be the gif HTMLElement.
loop_delay			Optional. The amount of time to pause (in ms) after each single loop (iteration).
draw_while_loading	Optional. Determines whether the gif will be drawn to the canvas whilst it is loaded.
show_progress_bar	Optional. Only applies when draw_while_loading is set to true.
Instance methods
load(callback)		Loads the gif specified by the src or rel:animated_src sttributie of the img tag into a canvas element and then calls callback if one is passed
load_url(src, callback)	Loads the gif file specified in the src argument into a canvas element and then calls callback if one is passed
play -				Start playing the gif
pause -				Stop playing the gif
move_to(i) -		Move to frame i of the gif
move_relative(i) -	Move i frames ahead (or behind if i < 0)
get_canvas			The canvas element that the gif is playing in. Handy for assigning event handlers to.
get_playing			Whether or not the gif is currently playing
get_loading			Whether or not the gif has finished loading/parsing
get_auto_play		Whether or not the gif is set to play automatically
get_length			The number of frames in the gif
get_current_frame	The index of the currently displayed frame of the gif
For additional customization (viewport inside iframe) these params may be passed:
c_w, c_h - width and height of canvas
vp_t, vp_l, vp_ w, vp_h - top, left, width and height of the viewport
A bonus: few articles to understand what is going on
