Viewport, Platform: Cleaned up xxx_UpdateMouseCursor() functions to make them more consistent. (#1542)

Viewport, Platform: Win32: Fixed handling of io.WantSetMousePos + added a bunch of comments. GLFW, SDL2: Added handling of io.WantSetMousePos. (#1542)

Scrolling: Fixed a case where using SetScrollHere(1.0f) at the bottom of a window on the same frame the window height has been growing would have the scroll clamped using the previous height. (#1804)

Viewport: Changed Monitor field to use Pos+Size (more consistent), changed FullMin,FullMax to MainPos,MainSize. Made main viewport accessible in PlatformIO on first frame. Fixed casing of ImGuiViewportFlags_TopMost flag. (#1542)

Combo: Horizontally offset items using WindowPadding instead of Indent, for consistency.

Internals: Made ContentsRegionRect absolute to reduce confusion. Renamed InnerRect to InnerMainRect, renamed WindowRectClipper to OuterRectClipped.

Fixed clipboard paste memory leak in SDL examples. (#1803)

Data types: Fix format srtings with leading blanks. Fix ColorEdit4() to not use obsolete formats (when using IMGUI_DISABLE_OBSOLETE_FUNCTIONS) (#643)

Apply fix from data_types branch, some widgets broken when format string doesn't contains a %. Broken by 92f0165. Data_types branch fix c5fb929.

Internals: Declaring DragBehavior, SliderBehavior in there (no warantee given) as they may be useful to custom widgets.

Moved DragScalar, InputScalar, SliderScalar to imgui.h as well as ImGuiDataType (#320, #643, #708, #1011)

Data types: Fixed empty format string (or no % specifier) breaking the parsing back of values.

Fix to allow compiling in unity builds where stb_rectpack/stb_truetype may be already included in the same compilation unit.

Settings: Added LoadIniSettingsFromDisk(), LoadIniSettingsFromMemory(), SaveIniSettingsToDisk(), SaveIniSettingsToMemory(), io.WantSaveIniSettings. (#923, #993)

Internals: Removed unnecessary allocation indirection for g.LogClipboard (this only made sense when there was a global context instance)

imgui_freetype: skip missing glyphs as well to match our stb loader (#1671, #1703)

Skip missing font glyphs V2 revert changes to stb_truetype.h (

Skip missing font glyphs to 1) avoid using space for missing glyphs and 2) allow merging fonts with overlapping ranges. Demo: Fixed displaying ? instead of greyed out empty box. (#1671, #1703)
