* Fonts: Comments, remove ImFontAtlas facing BuildGrowTexture(), BuildCompactTexture(). Make IsBuilt() obsolete.

* Fonts: ImFontAtlasBuildInit() uses the occasion to sync HasTexUpdates from imgui context, narrowing the scope where it isn't set.

* Fonts: Added back support for AddCustomRectFontGlyph()

Legacy path naturally works.

* (Breaking) Fonts: remove ImFontAtlasCustomRect which is now the same as ImTextureRect

* Fonts: Fixed/improved support for legacy backend. SetTexID() writes into our ImTextureData to keep the indirection, clear TexIsBuilt.

The idea is that a legacy backend can somehow add a if (!atlas->IsBuilt()) ImGui_ImplXXXXX_CreateFontsTexture() call _after_ Render() and some features are supported.

* Fonts: Removed BuildClearGlyphs(), conflated with ClearOutputData()

* Fonts: Added a bit of user facing tooling.

* Fonts: Reduced reliance on ImFontConfig::DstFont.

* Fonts: stb_truetype loader: Reworked scale handling to suggest this is not required caching.

* Fonts: Fixed leak due to indirectly recursing ImFontAtlasPackInit().

* Internals: added ImStableVector<> helper.

* (Breaking) Fonts: CalcWordWrapPositionA() -> CalcWordWrapPosition(), takes size instead of scale as this will be needed.

* Fonts: Baked system, with auto-bind, v10.

# Conflicts:
#	imgui_internal.h

* Fonts: clarify ClearTexData() as not supported with dynamic atlases.

* Fonts: Added PushFontSize(), PopFontSize() api. Added font_size param to PushFont() as well.

Fonts: Fixed PopFont() recovery.

(To squash into "Added PushFontSize(), PopFontSize() api."

* Fonts: Texture resizing favor growing height, halve pack nodes.

* Fonts: Debug dump to disk, debug log.

* Textures: Comments around ImTextureID type.

* Fonts: Baked system, v11.

* Fonts: Baked system, v12: support GlyphOffset / GlyphMinAdvanceX / GlyphMaxAdvanceX by scaling from ref value.

Overwriting cfg->PixelSnapH = true; in imgui_freetype is weird.

* Fonts: Reordered ImFont fields.

* Fonts: Allow PushFont/NewFrame/PopFont idioms to function.

* Fonts: PushFontSize() with -1 uses sources[0]'s size for now (backward compat design)

* Fonts: Fixed _OnChangedTextureID() asserting when calling on e.g. finalized drawlists.

* Fonts: Create a fallback glyph if none is available (fix crash on fonts with no fallback)

* Fonts: ImFontConfig: added GlyphExcludeRanges[].

* Fonts: Restore a functional AddCustomRectFontGlyph().

* Fonts: Exposed CompactCache(). Hide ClearCache().

* Fonts: ImFontFlags: ImFontFlags_NoLoadGlyphs + add ImFontFlags_LockBakedSizes

* Fonts: Baked system, fix subsequent sources overriding shared font metrics.

* Fonts: Added ImFontAtlasBakedSetFontGlyphBitmap().

* Fonts: reinstated ImFontAtlasBuildSetupFontCreateEllipsisFromDot() compatible with baked system, lazily baked.

* Fonts: Core allocates per-baked-per-src backend buffers, to allow having custom backend per font source. Backend BakedInit/Destroy/AddGlyph process a single source.

* Fonts: A font source can specify its own loader/backend.

* Fonts: Rework ImFontLoader signatures.

InitBaked may return false to signify this size is not supported.

* imgui_freetype: no need to store metrics locally.

* Fonts: Fallback glyph is now lazily loaded on demand (yay!). Moving ImFontBaked:: functions outside of class.

* Fonts: removed LockSingleSrcConfigIdx which isn't needed anymore since we don't load glyphs in ImFontAtlasBuildAddFont().

* Fonts: tidying up font scale logic.

# Conflicts:
#	imgui_internal.h

* Textures: Added ImTextureData::UsedRect.

# Conflicts:
#	imgui_internal.h

* Fonts: Added a ImFontFlags_NoLoadError flag to let user code try file paths. (3611)

* Fonts: Fixed various small warnings / build issues.

* Fonts: Obsolete GetGlyphRangesXXX() functions. Update font documentation.

* Fonts: ImFontConfig::GlyphExcludeRanges is owner and copied.

* Fonts: in ShowFontAtlas() preserve open-state for latest texture. Improve debug display.

* Fonts: Added UI to edit FreeType loader flags. Added ImFontAtlasBuildReloadAll() / ImFontAtlasBuildReloadFont()

* Demo: Exposed some basic UI in demo for sanity.

* Fonts: fixed a bug using size specified by secondary font sources.

* Textures: ImTextureData pixels are not immediately destroyed on setting ImTextureStatus_WantDestroy.

# Conflicts:
#	imgui_internal.h

* Textures: Added ImTextureRef::GetTexID() mostly for consistency.

Without it the logic may seem more confusing to grok for end-user.

* Fonts: fixed ImTextureID() being zero-cleared instead of using ImTextureUserID_Invalid. .

* Fonts: comments, tweaks, minor amends.

Comments, tweaks

* Fonts: avoid both ImTextureRef fields being set simultaneously.

* Fonts: detect if backend assign to texture on creation but doesn't update Status.

* Fonts: awkwardly alias old TexID name to TexRef using an union (may backtrack and just keep old name)

* Fonts: fixed legacy backend path preloading all sources sizes erroneously + failing to use ellipsis.

* Fonts: removed size rounding in AddFont() which breaks relative sizing of merged fonts (8502)

# Conflicts:
#	imgui.cpp

* (Breaking) Fonts: PushFont() default to preserve current font size.

* Fonts: fixed calling AddFontXXX not invalidating texture for legacy backends.

* Fonts: fixed GetCustomRectUV().

Fixing typo. Broken by fe598f7

* (Breaking) Fonts: rework GetCustomRect() api. Reintroduce ImFontAtlasRect.

* Fonts: added ImFontAtlasRectId_Invalid == -1

* Fonts: moved ImFontAtlasRectId back to public API.

* Fonts: added RemoveCustomRect().

+ internally add ImFontAtlasPackReuseRectEntry()

* Fonts: GC Compact All exposed in Metrics->Memory Allocations includes compacting texture data.

* Fonts: add optional out parameter to AddCustomRect()

* Fonts: tidying up.

* Fonts: changing loader/backend or loader flags may be done without losing custom rects. Sharing more code.

* Fonts: do not mark whole ImTextureData struct as IMGUI_API to fix warning when used in ImVector<> (8559)

* Fonts: internal rendering uses higher level functions.

* Fonts: misc tidying up.

* Fonts: fixed compaction gc-ing baked fonts used in the current frame + rename.

* Fonts: encode additional data in ImFontAtlasRectId to detect invalid id + added Rects debug browser.

* Fonts: packing of shared basic/line/cursor data uses more public API.

* Fonts: no need to load current baked on SkipItems window? + removed unused field.

Avoid baked staying active after GC. Might cause issues.

# Conflicts:
#	imgui.cpp

* Fonts: fixed unused variable warning.

* Fonts: ImFontAtlasBuildInit() is always called with atlas->Builder == NULL.

* Fonts: Extract ImFontAtlasBuildGetFontBaked() out of ImFont::GetFontBaked() mostly for consistency with upcoming changes + tweak locals in AddFont().

* Fonts: add ImFontGlyph::SourceIdx. Extract code out of DebugNodeFont() into DebugNodeFontGlyphesForSrcMask().

(src_mask unused in this commit)

* Fonts: rename many internal functions for consistency. No other changes.

* Fonts: shallow rework of ImFontAtlasBakedAddFontGlyph() to facilitate upcoming change.

* Fonts: make ImFont::Sources a vector.

Later it should become a ImSpan<>

* Fonts: rework toward reducing reliance on ImFontConfig::DstFont since we ought to separate them.

* imgui_freetype: moving data out of ImGui_ImplFreeType_FontSrcData.

The reasoning behind that we would ideally transition ImGui_ImplFreeType_FontSrcData to be shared between fonts using same source.

* imgui_freetype: removed anonymous namespace + extracting two functions outside of ImGui_ImplFreeType_FontSrcData.

* Fonts: comments on ImTextureData fields.

* Fonts: make RasterizerDensity a dynamic field. (temporarily exposed as SetFontRasterizerDensity()).

Moved FontAtlasOwnedByContext to OwnerContext

# Conflicts:
#	imgui.cpp
#	imgui_internal.h

* Fonts: proof of concept support for user textures.

# Conflicts:
#	imgui.cpp

* Fonts: fixed passing negative sizes to stb_truetype loader.

* Fonts: AddFont() functions now allow size_pixels==0.0f (only required when using certain functions)

Fonts: AddFont() funcitons allow size_pixels==0 for merged fonts.

* Examples: remove explicit font sizes from AddFontXXX() calls. Add commented out style.FontSizeBase assignment.

* Fonts: rename to ImFontAtlasBuildLegacyPreloadAllGlyphRanges().

* Fonts: fixed PopFont() broken recovery.

"misc_recover_1" test would assert in EndFrame()

* Fonts: amend UpdateCurentFontSize() early out optimization.

* Removed unneeded check in RenderText() loop + disable static analyzer false-positive warnings.

* imgui_freetype: fixed using legacy names.

* Fixed using IMGUI_DISABLE_DEMO_WINDOWS without IMGUI_DISABLE_DEBUG_TOOLS and without linking with imgui_demo.cpp

ref 0e769c5

* Fonts: UpdateCurrentFontSize() early out doesn't need to clear FontBaked.

This was meant when the code would be lower in the function (after updating e.g. g.FontSize) Amend 0e769c5.

* Windows: clicking on a window close button doesn't claim focus and bring to front. (ocornut#8683)

Added ImGuiItemFlags_NoFocus, ImGuiButtonFlags_NoFocus. Neither are well specified so marking as experimental.

* DrawList, Fonts: fixed ImFontAtlasTextureRepack() overwriting draw list shared data UV's etc. even when not bound. (ocornut#8694, ocornut#8465)

ImFontAtlasUpdateDrawListsSharedData() call from ImFontAtlasTextureRepack() would trigger this.
For simplicity we also track current atlas in ImDrawListSharedData, but we could probably use Font->ContainerAtlas.

* DrawList, Fonts: fixed PushFont()/AddImage() not restoring correct atlas texture id when using multiple atlas (ocornut#8694)

This also needs 24f7328.

* Windows: BeginChild(): fixed being unable to combine manual resize on one axis and automatic resize on the other axis. (ocornut#8690)

* Backends: GLFW: amend for multi-context support with multi-viewport. (ocornut#8676, ocornut#8239, ocornut#8069)

* Backends: DirectX12: fixed build on MinGW. (ocornut#8702, ocornut#4594)

* Backends: Allegro5: Fixed missing invisible mouse cursor, broken by ee8941e.

Amend 2a8c75f

* Backends: GLFW: Fixed not installing WndProc hook in all GLFW version, so AddMouseSourceEvent() logic was missing for some viewports.

* InputText: fix for InsertChars() to work on read-only buffer. (ocornut#8714, ocornut#8689, ocornut#8242)

Ill defined feature but memory editor use InsertChars etc on a read-only buffer.
`if (init_state)` block of InputTextEx() intentionally does not resize TextA, as unneeded.
Amend b2c7359
Amend e900571

* Fonts: AddFontDefault() adds to GlyphOffset.y instead of overriding it.

* Fonts: add comments and examples for GlyphExcludeRanges[].

* Fonts: fixed RenderText() asserting when crossing VtxOffset change boundaries. (ocornut#8720, ocornut#8465)

* Demo: fixed ID conflicts. (ocornut#8723)
