> The "KDE Classic" mouse cursor theme was implemented in code to source cursor images either from bundled XPMs or by rasterizing glyphs from the cursor font. This was used only when changing the cursor theme for already-running applications at runtime; for newly-started apps (and so including for new sessions) things relied on the special "#kde_legacy#" theme name triggering an equivalent fallback in Qt and libXcursor, by virtue of "#kde_legacy#" not actually existing.

This patch instead takes the approach of deleting the legacy code and reimplementing the "KDE Classic" theme as a modern image-based cursor theme by dumping the results of the old rasterization code into files.

In order to test the actual commit, please use the "drop-cursor-font-support" branch on git://anongit.kde.org:clones/kde-workspace/hein/kde-workspace (it's a fresh branch so it might not have made it to the mirrors at the time you read this). This was branched from master minutes ago.
