Combo: Removed unnecessary ClearActiveId() call (from era where active combo stored an id, now we just use popup functionality)

Added IsWindowAppearing().

Fixed C4267 conversion from size_t to int.

Demo: Minor coding style tweaks so bgfx copy needs less patching.

InputText: Merged bits from Navigation branch (inc. g.ActiveIdIsJustActivated is only set on the toggle).

Merged from Navigation branch (DragBehavior)

Merged from Navigation branch: ...

f71cdd1  Internal tidying up, moved code to CalcNextScrollFromScrollTargetAndClamp() so it can be reused by upcoming nav code.
c816e6c Fixed SetScrollX() handling of center ratio (which actually wasn't exposed publicly). (#323, #246)

Merged from Navigation branch: https://github.com/ocornut/imgui/commit/5cac4926c82a41253bd3540ce1bb4f50b0cfc146 fix title bar color of window under a modal window.

Added GetKeyPressedAmount() (from Nav branch) to be able to measure fast repeat rate accurately. Added internal CalcTypematicPressedRepeatAmount() function.

Merge various minor things (supposedly harmless) from Navigation branch into Master to reduce differences. Some code in NewFrame() has been moved around. (#787)

ProgressBar() fixed rendering when straddling rounded area. (#1296)

ImSwap() helper.

Internals: Renamed some ImGuiCorner enums.

ParseFormatPrecision() returns -1 for scientific noation 'e'/'E', RoundScalar() doesn't alter those.

Updated copyright date for 2017, updated Gallery link

Internals: Split some code out of NewFrame() into an Initialize() function.

Added IsMousePosValid() helper.

Fixed compilation with IMGUI_DISABLE_OBSOLETE_FUNCTIONS defined

IO: io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we'll now accept negative mouse coordinates.

Marked all fmt + va_list functions with format attribute so GCC/Clang can warn about them. Not ignoring -Wsuggest-attribute=format anymore for GCC/Clang.

Version 1.52 WIP

Version 1.51

Style: Tweaked default border (undo half-way from original c1e1e01) (#707)
