I've just noticed the tweak tool is very slow, far slower than the select tool. Moving the tweak cursor, even with a blank new document maximized, can take up to half a second if the window is maximized.
~suv, do you have the same kind of issues when testing recent cairo versions on OSX? If not, I guess it's a win32 specific bug or a problem with the compiler or the configure options.
On OS X 10.7.5, I do not observe any dramatic performance regressions with the select tool or tweak tool, comparing trunk builds using - GTK+/Quartz 2.24.17. cairo 1.12.14, pixman 0.28.2 to builds using - GTK+/X11 2.24.13, cairo 1.12.2, pixman 0.26.2 beyond known somewhat slower screen updates/redrawing with Quartz-based builds (this does not depend on cairo version).
[*] Possible limitation of my observations: I can only test with small screen resolutions (built-in monitor of 13" MBP laptop, no external monitor available) - any slow-downs which possibly are related to window size are likely not reproducible with a max document window size of 1280 x 800 px (size of fullscreen mode).
