reset token_buffer; current character is beginning of token

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)

canoncialize the selection so start <= end

API key: process text input [DEAR IMGUI] Added stb_textedit_text(), extracted out and called by stb_textedit_key() for backward compatibility.

returns 1 if the sum of two signed ints is valid (between -2^31 and 2^31-1 inclusive), 0 on overflow.

create the png data from post-deflated data

this function is designed to support animated gifs, although stb_image doesn't support it two back is the image from two frames ago, used for a very s

decode one 64-entry block--

get some unsigned bits

returns 1 if the product of two signed shorts is valid, 0 on overflow.

set up the kernels

read 16bit value and convert to 24bit RGB

find minimum y position if it starts at x1

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