Preload all glyph ranges for legacy backends. This may lead to multiple texture creation which might be a little slower than before.

On font removal we need to remove references (otherwise we could queue removal?) We allow old_font == new_font which forces updating all values (e.g.

Create a compact, baked "..." if it doesn't exist, by using the ".". This may seem overly complicated right now but the point is to exercise and impro

Setup main font loader for the atlas Every font source (ImFontConfig) will use this unless ImFontConfig::FontLoader specify a custom loader.

Load/identify special glyphs (note that this is called again for fonts with MergeMode)

This is essentially a free-list pattern, it may be nice to wrap it into a dedicated type.

Overwrite existing entry

Source buffer may be written to (used for in-place mods). Post-process hooks may eventually be added here.

You should not need to call this manually! If you think you do, let us know and we can advise about policies auto-compact.

Update texture identifier in all active draw lists

Called by NewFrame() for atlases owned by a context. If you manually manage font atlases, you'll need to call this yourself. - 'frame_count' needs to

Gamepad navigation mapping

This version is in theory thread-safe in the sense that no path should access ImGui::GetCurrentContext().

Sanitize format - Zero terminate so extra characters after format (e.g. "%f123") don't confuse atof/atoi - stb_sprintf.h supports several new modifier

- For scanning we need to remove all width and precision fields and flags "%+3.7f" -> "%f". BUT don't strip types like "%I64d" which includes digits.

Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return "" fmt = "%.3f" -> return fmt fmt =
