resizeBody Library Method
Short Description: Adjusts position and size of the animation canvas
Class: taccgl Class
Adjusts position and size of the animation canvas. Conceptually a taccgl™ animation
always runs on the complete HTML document displayed in the browser.
Technically, however, the animation is calculated only for that part of the
document that is actually visible in the browser window. Therefor the animation is shown
on an HTML 5 canvas that covers the visible part of the HTML document displayed.
Due to scrolling or resizing of the window, the visible portion of the document may
change. resizeBody then adjusts the animation canvas to cover the visible
part of the document. resizeBody is automatically called when
an animtaion starts. It also needs to be called whenever there is a resize or
scroll event while an animation is running. This normally takes place automatically
but sometimes needs to be done manually as documented in setHandlers.
