this would work for themes that use system colors but not the other ones.<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
theme::themechanged should cover both cases (and if it doesn't, it should)</p></pre>

but yeah, having it in theme doesn't make much sense, because technically the theme didn't change and you can't know from there if one of the svgs actually needs a repaint.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">so, what all of this suggests me is that the thing that would make most sense is actually use repaintneeded, and either:<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
a) just remove from the hash the id of this texture (multiple removes still possible tough)<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
b) event compress the clear()<br style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;" />
c) both of the above</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">So still having 3 times more hits than miss, so there's big room for improvement. Good news is that with this, we get a ~25% of memory and bandwidth save, in a per-item basis.</p></pre>
