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

Internals: Nav: Extracted code into a NavClampToVisibleAreaForMoveDir() + fix debug code + inline some functions, removed obsolete EndChild() comment.

TODO list update + Changelog and comments for #1803.

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: Comments (#923, #993)

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)

Ran a spell checker for sanity.

Examples: DirectX9: Comments, updated changelog, notes about usage of imconfig.h (#1790, #1687)

add renderstate D3DRS_SHADEMODE for Dx9 impl ...

add backuping transform for Dx9 impl
(#1790, #1687)

SliderScalar, VSliderScalar(): Support for any data types. Tested with various ranges/limits. Note that Drag/Slider/Input currently fail if the format string doesn't preview the actual value. Will fix next. (#320, #643, #708, #1011)

Internals: A few selected math helpers are now using template to handle all supported types. Added ImPow() to wrap float/double in a standard manner without calling pow(double) when not needed in Drag code.

Internals: Data types: Made format string optional. DragBehavior: Moved a bit of code outside of the template. Slider tidying up. Removed unnecessary call to fabsf().

DragFloat, DragInt: Default format string is none is passed to the function. Fixed demo using old style %.0f.

Made IMGUI_DISABLE_OBSOLETE_FUNCTIONS exceptionally not affect the layout of ImGuiIO. (#1695)

Internals: Missing const, some renaming. Tweak legacy fast path.

DragInt, DragScalar: Actually made the fast-past handle the now-most-common case..

DragInt: Patch old format strings to replace %f by %d when using the DragInt() entry point. (#320, #643, #708, #1011)

Ran a spell checker for sanity.

Internals: Tidying up internal helpers. Fixed a case ImParseFormatTrimDecorations() can return an off by one (out of bound) pointer if the format string is invalid. Extracted ImParseFormatFindEnd() out of TrimDecorations so we can use it to find the format type and replace the %f in old Int apis.

Internals: Fixed DragInt* default format string. InputScalar(), InputScalarN(), removed InputFloatN(), InputInt(). Note that DragInt2/3/4 will %f format strings will currently be broken. (#320, #643, #708, #1011)
