<pre>I think we have to check the modification time of the .desktop file as well. Technically, the theme file itself could have been modified to point to a different SVG file.</pre>

<pre style="margin: 0; padding: 0;">KGameRenderer is a small SVG->pixmap rendering framework for use in KDE games. I want to add it to libkdegames in the 4.6 cycle. For the story behind it, see http://kde.markmail.org/message/plfkwfeoni6nvpk2
Most important features:
- management of SVG themes (via KGameTheme and QSvgRenderer)
- reading of animated sprites (i.e. multiple SVG elements which are displayed one after the other to obtain an animation)
- multithreaded rendering
- two caching levels (in-process QHashes and shared KSharedDataCache)
- integration with QGraphicsView through the KGameRenderedItem class
- integrability with any existing implementations through the KGameRendererClient base class</pre>

<pre style="margin: 0; padding: 0;">As part of a general refactoring, I have ported KDiamond to KGameRenderer in a local Git working branch which is available from git://git.bethselamin.de/kdegames-work.git (branch "kgamerenderer"). The port is stable and much faster, both in animation performance and startup time. Also, memory usage is about 1 MB lower in both the cold-start and warm-start scenario (i.e., without and with disk caches).</pre>
