Description

The SVG file renders the file's document width/height as the first choice.

Motivation and Context

In some files.

<svg width="33" height="53" viewBox="0 0 33 53" fill="none" xmlns="http://www.w3.org/2000/svg">
	<path d="M16.3576 0.666687L16.0095 1.85009V36.1896L16.3576 36.5371L32.2976 27.115L16.3576 0.666687Z" fill="#343434"/>
	<path d="M16.3578 0.666687L0.417816 27.115L16.3578 36.5372V19.8699V0.666687Z" fill="#8C8C8C"/>
	<path d="M16.3575 39.5552L16.1613 39.7944V52.0268L16.3575 52.6L32.307 30.1378L16.3575 39.5552Z" fill="#3C3C3B"/>
	<path d="M16.3578 52.5998V39.5551L0.417816 30.1377L16.3578 52.5998Z" fill="#8C8C8C"/>
	<path d="M16.3575 36.537L32.2973 27.1151L16.3575 19.8699V36.537Z" fill="#141414"/>
	<path d="M0.417816 27.1151L16.3576 36.537V19.8699L0.417816 27.1151Z" fill="#393939"/>
</svg>

On the pixel 3xl:
view box size. width: 33 height: 53 dpi:96
if we use renderToPicture()  Picture's size:width: 608 height: 977
if we use renderToPicture(DocumentWidth,DocumentHeight) Picture's size. width: 608 height: 1908
the view'size:width: 608 height: 1908

the picture's size should be determined based on the canvas size or document size.
