OpenGL3 Render function. Note that this implementation is little overcomplicated because we are saving/setting up/restoring every OpenGL state explici

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 =

Trim str by offsetting contents when there's leading data + writing a \0 at the trailing position. We use this in situation where the cost is negligib

Find end-of-line. Return pointer will point to either first \n, either str_end.

This is only used in the path where the multiline widget is inactivate.
