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)

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

Internals: InputScalarEx: Tweak internals so there is a fast path for the simple case. ...

(in particular because it makes it clear what the extra code is for, so people tempted to create their own InputText data transform/handler understand how little is actually needed)

Internals: Added ImGuiDataType_Uint32 data type which is usable with InputScalarEx().

Nav: Fixed hovering a Selectable() with the mouse so that it update the navigation cursor. Fixed c8b9b2c6 which was incorrect (#787)

Internals: Tweaked ParseFormatPrecision(), clarified its more limited purpose, allowing 2-digits precisions since it makes (some) sense for doubles. (#648)

DragFloat, SliderFloat: Rounding scalar using the provided format string instead of parsed precision. (#648)

DragFloat/SliderFloat internal InputScalar trip trailing decoration off the format string when presenting an edit box to the user. (#648)

DragFloat/SliderFloat internal InputScalar relies on the user supplied format string to format and parse value. (#648) ...

The trailing text after the format will be displayed in the InputText but not affect back parsing. Ideally we can try to strip it later.

Clarified usage of ListBoxHeader() before we rename those functions + fixed demo code that didn't honor it correctly. (#1783)

DragDrop: Removed const qualifier from ImGuiPayload 's void* data, easing casting on user side.

Demo: Fixed demo from using obsolete functions.

InputFloat,InputFloat2,InputFloat3,InputFloat4: Added variations taking a more flexible and consistent optional "const char* format" parameter instead of "int decimal_precision". This allow using custom formats to display values in scientific notation, and is generally more consistent with other API. Obsoleted functions using the optional "int decimal_precision" parameter. (#648)

Renamed all "display_format" arguments to "format" to emphasis that they also affect rounding of values. (#648, #642)

SliderFloat, DragFloat: Fix to allow input of scientific notation when Ctrl+Clicking a slider or drag, matching the change done in c19b2781 for InputFloat(). (#648, #1011)

DragFloat, DragInt: Cancel mouse tweak when current value is initially past the min/max boundaries and mouse is pushing in the same direction (keyboard/gamepad version already did this).

Internals: DragBehavior: tweaks internals.

Internals: Reordered parameters of DataTypeFormatString() internal helper functions and shallow tweaks.

InputText: Fixed returning true when edition is cancelled with Esc and the current buffer matches the initial value.

Comments, minor tweaks

Fixed static analyzers warnings with bool literals (#1775) ...

* Use `false` instead of `0` for a bool literal.
* Simplify calls to RadioButton to not need bool literals.

Comments (#1695)

Added IMGUI_CHECKVERSION() macro to compare version string and data structure sizes in order to catch issues with mismatching compilation unit settings. (#1695, #1769)

Misc: Stop moving window if mouse position becomes invalid. Flagged menus are _NoMove for sanity.
