<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I've run your native_render_frame branch for a bit, some observations on my system:
- It mostly works
- taskbar doesn't find some elements in the svg, leading to lots of messages like this:
plasma_shell(11872)/default QSvgTinyDocument::draw: Couldn't find node normalbottomright. Skipping rendering.
- we seem to be hitting a few slow code pathes, which mean that I'm getting some smaller and longer freezes
- memory usage has gone up quite a bit, from 178MB to 328MB
- I'm seeing lots of threads of plasma-shell in ps
I like the idea, though, and I think those issues are something that can be sorted out. Looking at the code, it looks pretty clean so far, so nice work! </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;">Aye, it turns out there's a reason Plasma::FrameSVG is really big; and I'm basically recreating the most complex method inside that branch. Note that branch contains a lot more stuff than that's in this review.
I need to fold back the things I've improved/learned from this review into that frame branch.
I'm going to try to IconItem next I think, it's less menacing, but contains an animation which is exciting.</pre>

it is _not_ the same as the native_render_frame branch. </pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">The rationale behind this patch is on the mailing list in the thread "Minutes Monday"
This doesn't boost performance or save memory much, but it paves the way for texture sharing, faster resizing, and plenty of other things.
Based on Frederick's comment I have reverted my changes to use QImage everywhere, otherwise we lose out on the local QPixmap cache in KImageCache.
Changes to plasmacore are minimal.
I'm currently porting FrameSVG which is where we should see more gains, but I thought I should get this reviewed/merged in parallel.
I have only seen one regression which is in the analog clock.
Some odd code in the analog clock (by me apparently!) means the width is dependent on the current width, which due to some changes in this patch ends up in a constant spiral getting to infinitely sized and explode.
Changelog (in reverse order):
Remove manual isDirty tracking in SvgItem
Always resize the node geometry on resizes
Update to paint to fill the size of the object, not the size of texture
Fix leaking texture
Add convenient QImage image() getter in SVG
Avoid repainting if node is not changed
Render SvgItem natively rather than going through QQuickPaintedItem</pre>
