This is already called while stepping. The ONLY reason you may want to call this is if you passed INT_MAX to ImGuiListClipper::Begin() because you cou

Scrolling happens only in the central section (leading/trailing sections are not scrolling)

Clear and initialize empty settings instance

Adjust flags: default width mode + stretch columns are not allowed when auto extending

Store ImGuiTreeNodeStackData for just submitted node. Currently only supports 32 level deep and we are fine with (1 << Depth) overflowing into a zero,

Initialize before use in a new frame. We always have a command ready in the buffer. In the majority of cases, you would want to call PushClipRect() an

This is used by ImGui::PushFont()/PopFont(). It works because we never use _TextureIdStack[] elsewhere than in PushTextureID()/PopTextureID().

traverse the layout to locate the nearest character to a display position

API click: on mouse down, move the cursor to the clicked location, and reset the selection

discard the oldest entry in the undo list

API drag: on mouse drag, move the cursor and selection endpoint to the clicked location

find the x/y location of a character, and remember info about the previous row in case we get a move-up event (for page up, we'll have to rescan)

stb_textedit internally allows for a single undo record to do addition and deletion, but somehow, calling the stb_textedit_paste() function creates tw

canoncialize the selection so start <= end

[DEAR IMGUI] Added stb_textedit_text(), extracted out and called by stb_textedit_key() for backward compatibility.

find minimum y position if it starts at x1

rects array must be big enough to accommodate all characters in the given ranges

check if a utf8 string contains a prefix which is the utf16 string; if so return length of matching utf8 string
