wip 2009-09-21:
FIX: fixed hack for tiny taskbars, should fix placement of text on thin taskbars
FIX: expansion state update (on desktop change and other state changes)
NEW: Michal Odstrčil has written a new and better layout "Maximum Squeeze Ratio".
This layout isn't 100% completed yet (Michal is still working on the "only group when taskbar is full" feature) and also the name might change.

FIX: also delay item expansion (not only collapse)
NEW: several alternative taskbar layouts to choose from. which one is the best? which one can I drop? each one has pros and cons.
 * By Taskbar Shape: the layout used until now
 * Maximum Squeeze: uses the task item size like it would need to use the defined maximum rows
 * Fixed Item Number per Row: uses a fixed definable number of items per row
 * Fixed Maximum Item Height: never let the task items get bigger than the defined maximum item height
NEW: french translation, thanks to Sergio Guibert
Improvement: improved the settings dialog

wip 2009-09-08:
FIX: regression where animation duration for tooltip showing delay was ignored
FIX: small fix to polish translation
HACK: added hack for plasma themes that define a to large margin

FIX: calculation of preferred size (seems still not to be propagated in some cases)
FIX: better (diagonal!) tooltip movement, especially for multiple rows or rotated view
FIX: fixed bug when dropping task to pager and it gets locked or not removed from the taskbar

wip 2009-09-05b:
FIX: expansion state/animation of newly added task items

wip 2009-09-05a:
FIX: added short delay for tooltip switching to fix:
 * reaching tooltips of task items in lower rows
 * moving to the tooltip but accidently hovering another task item for a very short time

wip 2009-09-05:
NEW: multirow support! that was hard for my small brain!
NEW: always 'scroll' (move) tooltips when using the wheel
NEW: exposing fps setting in UI
FIX: fixed crash when using wheel on tooltip (in rare cases)

wip 2009-09-02:
NEW: more 'smooth' animated manual task sorting. This uses QTimer for the
animation because I find Plasma::Animator much to limited to do such an
animation. I hope kinetic will be more convenient.
FIX: fixed a rare crash. let's hope I didn't introduce a new one.
NEW: now you can scroll the text on animated text labels per dragging it.
just in case it scrolls to fast/slow for your taste.
NEW: implemented scrolling of tooltip on mouse wheel when the preview is
outside of the screen. thanks to ssri for noticing this.
Improvement:
Tooltips should now be a bit better glued to their task items.

wip 2009-08-28:
NEW: work on i18n and german translation (thanks to xadras for reminding me)

wip 2009-08-26:
NEW: support for native plasma tooltips and for disabling tooltips all together

wip 2009-08-25:
Improvements:
vertical ordering of tooltip in vertical form factors
only show preview area when previews are available (for all those who don't like the previews)
better (still not perfect) tooltip movement start position
don't collapse tasks when hovering tooltip

wip 2009-08-24a:
FIX: hopefully fixed another tooltip movement regression

wip 2009-08-24:
FIX: reworked tooltip movement (still not perfect on short animation duration)
FIX: improved tooltip placement, thanks to Michal Odstrčil
NEW: implemented D'n'D to tooltips. however, sometimes this gets stuck and I have no idea why.
HACK: it seems like the pager does not support drops of task groups so only drop the first task of the group
FIX: fixed scrolling over tooltips that didn't work together with normal hovering

wip 2009-08-23a:
FIX: hopefully fixed tooltip bug which was introduced in the last version

wip 2009-08-23:
overhaul of animations of the task item (color, frame, expansion)
update tooltip move animation when task is expanding
mouse wheel to switch through window previews
used other border for window previews (is this better or worse?)
highlight tooltip task icons on hover
use only current screen geometry for tooltip placement
fixed annoying off by one pixel bug in tooltip movement
added cmake requires for KDE4Workspace

wip 2009-08-21:
FIX: tooltip stealing on window title change bug

wip 2009-08-20:
FIX: (ugly) workaround for kwin highlight window effect bug
NEW: allow animation duration time in ragne [0, 500] ms.
FIX: bug that occurred with duration time = 0 (but possibly also in other corner cases)
REMOVED: "Show Border Around Window Previews" options (always show it)

wip 2009-08-19:
NEW: highlight hovered previews
NEW: right click for context menu on previews. for some reason the 'crash on
right click' bug disappeared with this change.

wip 2009-08-18:
Renamed to Smooth Tasks. :)
A lot of refactoring (now I'm using namespaces).
NEW: close icon is only shown when hovering the corresponding preview
NEW: transitions between close icons visual states (hidden, shown, highlighted)
are now animated

wip 2009-08-17:
FIX: hopefully really fixing tooltip placement issues on multihead systems

wip 2009-08-16:
FIX: probably fixed another rare crash on exit. this occurs when the tooltip
is already deleted but the task items aren't (they access the tooltip in their
destructor)

wip 2009-08-15:
FIX: fixed layout spacing
Improvements:
faster scroll back of the text when stopping hovering
delete previews when tooltip is hidden

wip 2009-08-14:
FIX: tooltips for starting tasks
NEW: resize previews when their windows are resized. I don't know if I keep
this because under some circumstances (showing grouped tooltips for several
automatic and continuous fast resizing windows) this can lock up kwin.

wip 2009-08-13:
some minor improvements on the code (e.g. removed redundancy a bit)

wip 2009-08-12:
NEW: scroll text of labels on mouse-hover when the text is to big for the
label
FIX: correct placement of non-square icons
IMPROVEMENT: use KIconEffect for close button highlighting

wip 2009-08-11:
tiny layout improvement: give text enough room to not crop descenders

wip 2009-08-10a:
Forgot to add new source files.

Fadeout long task names in tooltips.

wip 2009-08-09:
NEW: update tooltip when task is added/removed
improved layout
made border around previews optional

wip 2009-08-08:
less flicker when moving between tooltip and same task item
NEW: show number of grouped tasks in taskbar item (copied code from KDEs
original taskbar plasmoid)
NEW: window peeking using kwins highlight window effect
NEW: animated scrolling of tooltip when its to big for the screen (move your
cursor to the screen edges)
NEW: tooltip moves animated when moving mouse over taskbar items
KNOWN ISSUE: sometimes when you move the mouse fast over the taskbar items the
tooltip contains garbage
