Throw an exception if the given arguments are invalid.

The combination of clip() and globalCompositeOperation was not supported.
Shapes with shadow were displayed in the wrong position when clipped.
arcTo() occasionally drew a straight line of infinite length by error.
arc() didn't add the start point to the subpath when the startAngle and the endAngle were the same.
restore() didn't restore the clipping region correctly.
clearRect() should not clear the pixels outside the clipping region.
Special characters in a url need to be escaped when passed to Flash.
toDataURL("image/jpeg") must composite the image to a black background.
Many minor bug fixes thanks to the canvas test suite developed by Philip Taylor.

Line styles were not set when the strokeStyle attribute was a CanvasGradient or CanvasPattern object.
Patterns were painted ignoring the globalAlpha attribute.
Patterns assigned to the strokeStyle attribute were not transformed.
The transformation matrix mistakenly affected the shadowOffsetX and shadowOffsetY attributes.
arc() didn't add the end point to the subpath when the central angle was greater than 2 pi.
closePath() must do nothing if the context has no subpaths.
IE8 didn't preload the swf file when the URL was a relative one.
Resize event canceled createLinearGradient().
The disableContextMenu option disabled mouse clicks on the outside of the canvas element.
