- update to 2.6.3
dropped libpng patch
New features over 2.5.26:
* Support libpng 1.4 and 1.5.0's slightly newer APIs
* New extended variable $[w.visiblename]
* Style matching now honours the window's visible name
* New style InitialMapCommand allows to execute any command when
a window is mapped first.
* New option to PrintInfo, "bindings" which prints out all of the
Key, PointerKey, Mouse and Stroke bindings which fvwm knows about.
* New differentiated options for SnapAttraction when snapping
against screen edges:
* New option to the BugOpts command
* New BugOpts option QtDragnDropWorkaround to work around an oddity
in handling drag-n-drop events to Qt applications.
* New MenuStyle "UniqueHotkeyActivatesImmediate" and its negation
"!UniqueHotkeyActivatesImmediate" to retain the menu until the
user presses one of the menu keybindings to enact that change in
the case where there's only one item defined in the menu at the
specified hotkey.
* New Style commands
* New Resize argument to direction
* Couple of changes to the Move command:
* The EWMH working area is now honoured by default.
* To move a window ignoring the working area, the option "ewmhiwa"
can be used, similar to how the Maximize command works.
* New expansion placeholder $[pointer.screen] to return the screen
number the pointer is on. (forwarded request 98593 from vitezslav_cizek)
