Merge remote-tracking branch 'origin' into 2016-07-navigation

ImFormatString() Fixed an overflow handling bug with implementation of vsnprintf() that do not return -1 (#793)

Nav: Comments. Fixed two -Wall warnings. Removed unused function. (#787)

Nav: Fixed Selectable() crash introduced earlier today in 43ee5d73 + added comments/assert (#323)

Nav: NavActivateId, NavInputId are no repeat actions. Repeat buttons handle it themselves already anyway. (#323)

Merge remote-tracking branch 'origin' into 2016-07-navigation

Nav: Removed unnecessary test following 49ca1c2 (#323)

Nav: InitDefaultRequest saves a fallback item so PadMenu on a collapsed window gets us to the collapse button (#323)

Close button submitted after collapse button. Should have no effect. Consistent with expectation & will be used as fallback for nav (#323)

Nav: Undo 87eb749cbc, agressively including nav focus test in IsItemHovered() (#323)

Nav: Fixed nav highlight clipping (affected non non-menu items within menubar) (#323)

Nav: Process and apply mouse move request immediately after move request result comes (#323)

Internal tidying up, moved code to CalcNextScrollFromScrollTargetAndClamp() so it can be reused by upcoming nav code.

ImRect: Added Translate() helper, removed redundant and misleading Reduce()

Added IsItemHoveredOrFocused() (provisional name), better handling of popup/tooltip positioning when using mouse+nav (#323)

Nav: Fixed entering child with PadActivate not setting ActiveIdSource to Nav (#323)

Nav: Hovering MenuItem/Selectable with mouse makes NavId, matching what seems to be Windows beahvior at least for menus (#323)

Nav: Mouse pos passed to backend always rounded, so that lossy application of non-integer mouse pos doesn't lead to undesirable movement (#3

Nav: Clearing mouse hover flag using MouseClicked[] test instead of MouseDown[] so that invalid mouse button won't keep breaking nav (#323)

Nav: Tidying up. Comments. (#323)

Nav: Fixed a bug where mouse positioning requests would be sent while opening submenus with mouse (#323)
