Font: Narrow ellipsis: various minor stylistic tweaks (#2775)

Font: implement a way to draw narrow ellipsis without relying on hardcoded 1 pixel dots. (#2775) ...

This changeset implements several pieces of the puzzle that add up to a narrow ellipsis rendering.

## EllipsisCodePoint

`ImFontConfig` and `ImFont` received `ImWchar EllipsisCodePoint = -1;` field. User may configure `ImFontConfig::EllipsisCodePoint` a unicode codepoint that will be used for rendering narrow ellipsis. Not setting this field will automatically detect a suitable character or fall back to rendering 3 dots with minimal spacing between them. Autodetection prefers codepoint 0x2026 (narrow ellipsis) and falls back to 0x0085 (NEXT LINE) when missing. Wikipedia indicates that codepoint 0x0085 was used as ellipsis in some older windows fonts. So does default Dear ImGui font. When user is merging fonts - first configured and present ellipsis codepoint will be used, ellipsis characters from subsequently merged fonts will be ignored.

## Narrow ellipsis

Rendering a narrow ellipsis is surprisingly not straightforward task. There are cases when ellipsis is bigger than the last visible character therefore `RenderTextEllipsis()` has to hide last two characters. In a subset of those cases ellipsis is as big as last visible character + space before it. `RenderTextEllipsis()` tries to work around this case by taking free space between glyph edges into account. Code responsible for this functionality is within `if (text_end_ellipsis != text_end_full) { ... }`.

## Fallback (manually rendered dots)

There are cases when font does not have ellipsis character defined. In this case RenderTextEllipsis() falls back to rendering ellipsis as 3 dots, but with reduced spacing between them. 1 pixel space is used in all cases. This results in a somewhat wider ellipsis, but avoids issues where spaces between dots are uneven (visible in larger/monospace fonts) or squish dots way too much (visible in default font where dot is essentially a pixel). This fallback method obsoleted `RenderPixelEllipsis()` and this function was removed. Note that fallback ellipsis will always be somewhat wider than it could be, however it will fit in visually into every font used unlike what `RenderPixelEllipsis()` produced.

ImDrawList: clarified the name of many parameters so reading the code is a little easier. (#2740)

Version 1.73 WIP

Version 1.72b (patch for nav)

Version 1.73 WIP

Version 1.72

ImDrawList: Using ImDrawCornerFlags instead of int in various apis. ...

Demo: Using ImGuiColorEditrFlags instead of int.

Renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Keep redirection typedef (will obsolete).

Internals: ImGuiListClipper using absolute coordinate (instead of relative one). Minor no-op tweaks + ImDrawListSplitter assert

Style: Attenuated default opacity of ImGuiCol_Separator in Classic and Light styles.

Word-wrapping: Fixed overzealous word-wrapping when glyph edge lands exactly on the limit. Because of this, auto-fitting exactly unwrapped text would make it wrap. (fixes initial 1.15 commit, 78645a7d).

Disable -Wpragmas warning in GCC to avoid relying on version checks, as unusual/forks/mods don't appear to always have same warning<>version. (#2618) ...

+ Fix version number in imgui.h

ImDrawList: Fixed CloneOutput() helper crashing. Also removed unnecessary risk from ImDrawList::Clear(), draw lists are being clear before use each frame anyway. (#1860)

ImDrawList::ChannelsSplit(), ImDrawListSlitter: Fixed an issue with merging draw commands between channels 0 and 1. (#2624) Introduced by cef88f6.

Version 1.72 WIP

Version 1.71 + comments

Readme, comments, dear imgui prefixes

ImDrawListSplitter: Don't merge draw commands when crossing a VtxOffset boundary + Renamed fields ImDrawChannels to consistently suggest those are internal structures.

ImDrawListSplitter: Fix idx offset when merging (cef88f6) (#2591)

Internals: Added drawlist and color arg to RenderArrow(), RenderBullet(). Reordered args for RenderPixelEllipsis.

ImDrawListSplitter: Support merging consecutive draw commands straddling two channels. Support zero-init.

ImDrawListSplitter: extracted out of ImDrawList. Down the line we may obsolete the ImDrawList functions and encourage users to store the splitter aside, in the meanwhile ImDrawList holds a splitter. ...

(This will allow columns/table to recurse.)

ImDrawList: Fix broken channel splitting (another issue when the first channel is empty) (#2591) + fixed warnings with newer VS

Include <alloca.h> also when __SWITCH__ is defined (#2595) ...

Fixes compilation with devkitPro for Nintendo Switch
