Examples: Win32: Using IsChild() to be compatible with windows created within a parent. (#1951, #2087, #2156, #2232)

Examples: DirectX9: Explicitly disable fog (D3DRS_FOGENABLE) before drawing in case user state has it set. (#2288, #2290)

EditorConfig: Further tweaks (#2038)

Add editor config for 4 spaces instead of tab.

ImDrawList: Fixed AddCircle(), AddCircleFilled() angle step being off, which was visible when drawing a "circle" with a small number of segments (e.g. an hexagon). (#2287) [@baktery] ...

+ Demo tweaks

Various tweaks and fixes as suggested by PVS Studio (thanks PVS Studio!)

Examples: DirectX12: Targeting 10.0.14393.0 instead of 10.0.16299.0 (available on AppVeyor, and higher version doesn't seem necessary).

FreeType: Minor tweaks previous commit (#2285)

By default ImGuiFreeType will use ImGui::MemAlloc()/MemFree(). ...

ImGuiFreeType::SetAllocatorFunctions() can be used to specify custom allocator.

Examples: Win32: Added support for XInput games (if ImGuiConfigFlags_NavEnableGamepad is enabled).

Examples: Win32: Using GetForegroundWindow() instead of GetActiveWindow() to be compatible with windows created in a different thread. (#1951, #2087, #2156, #2232) [many people]

Version 1.68 WIP

TODO update + internals: changed order or ImGuiLayoutType enums to allow using them for indexing.

Fixed cursor issue caused by 6890e08b when calling BeginChild/EndChild multiple times to reappend into a same child window. (#2282)

Version 1.67

DragFloat: Fixed broken mouse direction change with power!=1.0. (#2174, #2206) [@Joshhua5]

Added a bunch of diagnostic ignore to cope with Clang -Weverything being absurd. Also fixed two legit warnings. (#2277)

Merge branch 'atlas_fixes'

Demo: Fixed bounds of DragFloat in Clipping section to avoid passing zero-sized to InvisibleButton().

FAQ entry, moved ImTextureId, Gallery links.

imgui_freetype: Fixed redundant FT_Load_Glyph() calls, unused parameters, and compilation warning/error. (#2270)

ImFontAtlas: Fixed allocating for last bit (would only affect is that last codepoint is a multiple of 32). (#2270)

ImFontAtlas: Rewrote FreeType based builder. ...

- Fixed abnormally high atlas height. (#618)
- Fixed support for any values of TexGlyphPadding (not just only 1). (#618)
- Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth). (#618)
- Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233, #618)
- Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas. (#618)

ImFontAtlas: Rewrote stb_truetype based builder. ...

- Atlas width is now properly based on total surface rather than glyph count (unless overridden with TexDesiredWidth).
- Fixed atlas builder so missing glyphs won't influence the atlas texture width. (#2233)
- Fixed atlas builder so duplicate glyphs (when merging fonts) won't be included in the rasterized atlas.

Internals: Added ImBoolVector helper.

imgui_freetype: Minor tweaks and comments.

ImVector: Added size_in_bytes() helper.

ImFontGlyphRangesBuilder: Using 32-bits fields for storage instead of 8-bit ones, comments, todo.

ImVector: Made reserve() another silly one-liner. It's not longer than other functions and our weird obsessions deserve to be carried with stringent consistence. + Comments

ImVector: Made a struct. Using T/T* in the code instead of value_type/iterator. Renamed index_from_pointer() to index_from_ptr() (was not documented, added in 1.63, users not supposed to use ImVector, hopefully not a big deal).
