<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Do we want to have size and devicePixelRatio separate in the cache ID?
It means if I request 20x20 at ratio 1.0, it will have a different ID to 40x40 at ratio 2.0 despite being (as I understand it) visually identical?</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">the only problem is that when the svg is not scaled, instead of the actual size, "Native" gets in the id instead.
now i don't remember the reason anymore, but it breaks in that case</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">(/me digs down in git history)
at that point you don't know yet what is the size of the element (or the whole svg for what matters), because the renderer doesn't exist yet (and one of the points of the cache is to avoid to instantiate the svg renderer altogether if possible)</pre>

on the component side, it sets the devicepixelratio of the svg and framesvg with units.
devicepixelratio is always set integer in the svg, so needs at least 192dpi to double up.
(it needs to be integer to have lines contained inside a svg piece to keep being pixel aligned)</pre>
