	# Deflate compression using Canvas 2d API

	Canvas API provides HTMLCanvasElement#toDataURL, which allows serialize canvas image to png image. I do not know about result png format (how many bits per pixel and there is alpha channel or not, may be palette or grayscale image). WHATWG spec also do not points this ie its UA dependent. Anyway basic rules:
	+ browsers do not supports images with width or height > 20 000 px => we use square image instead linear(1X or X1)
	+ if alpha component of canvas data eq 0 => browser reset red, green, blue to 0 too even if globalCompositeOperation = 'copy'
	+ even if globalCompositeOperation = 'copy', globalAlpha = 1.0, dest alpha of pixel eq 255 - browser blends src image data when you perform putImageData and original red, green, blue components corrupts due floating point errors. For example we have one pixel [1,129,130,131], let see putImageData(this pixel); getImageData() -> [1,128,130,131]; drawImage(toDataUrl()); ; getImageData -> [1,126,128,131] =>
