Functions

OpenGL2 Render function. Note that this implementation is little overcomplicated because we are saving/setting up/restoring every OpenGL state explici

Based on stb_to_utf8() from github.com/nothings/stb/

Not optimal but we very rarely use this function.

Computes RGB intensity and sets specified channels to that value. Any combination of RGBA allowed.

Pass text data straight to log (without being displayed)

Helper for ColorPicker4()

Note: as with every ImDrawList drawing function, this expects that the font atlas texture is bound.

Save current stack sizes for later compare

Clear and initialize empty settings instance

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

Pop trailing draw command (used before merging or presenting to user) Note that this leaves the ImDrawList in a state unfit for further commands, as m

Initialize before use in a new frame. We always have a command ready in the buffer.

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

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
