/// - 2018/01/05 (3.00.0) - BREAKING CHANGE: The previous color picker API was broken
/// because of conversions between float and byte color representation.
/// Color pickers now use floating point values to represent

/// comes in effect if you pass in zero was row height argument.
/// - 2017/06/08 (1.40.0) - BREAKING CHANGE: while not directly API breaking it will change
/// how layouting works. From now there will be an internal minimum
/// row height derived from font height. If you need a row smaller than
/// that you can directly set it by `nk_layout_set_min_row_height` and
/// reset the value back by calling `nk_layout_reset_min_row_height.
/// - 2017/06/08 (1.39.1) - Fixed property text edit handling bug caused by past `nk_widget` fix.
/// - 2017/06/08 (1.39.0) - Added function to retrieve window space without calling a `nk_layout_xxx` function.

/// - 2017/01/21 (1.32.1) - Fixed slider behavior and drawing.
/// - 2017/01/13 (1.32.0) - Added flag to put scaler into the bottom left corner.
/// - 2017/01/13 (1.31.0) - Added additional row layouting method to combine both
/// dynamic and static widgets.

/// - 2016/12/31 (1.29.2) - Fixed closing window bug of minimized windows.
/// - 2016/12/03 (1.29.1) - Fixed wrapped text with no separator and C89 error.

/// - 2016/11/18 (1.28.2) - Fixed memory leak caused by popup panel allocation.
/// - 2016/11/10 (1.28.1) - Fixed some warnings and C++ error.
/// - 2016/11/10 (1.28.0) - Added additional `nk_button` versions which allows to directly
/// pass in a style struct to change buttons visual.
/// - 2016/11/10 (1.27.0) - Added additional `nk_tree` versions to support external state
/// storage. Just like last the `nk_group` commit the main
/// advantage is that you optionally can minimize nuklears runtime
/// memory consumption or handle hash collisions.
/// - 2016/11/09 (1.26.0) - Added additional `nk_group` version to support external scrollbar
/// offset storage. Main advantage is that you can externalize
/// the memory management for the offset. It could also be helpful
/// if you have a hash collision in `nk_group_begin` but really
/// want the name. In addition I added `nk_list_view` which allows
/// to draw big lists inside a group without actually having to
/// commit the whole list to nuklear (issue #269).
/// - 2016/10/30 (1.25.1) - Fixed clipping rectangle bug inside `nk_draw_list`.
/// - 2016/10/29 (1.25.0) - Pulled `nk_panel` memory management into nuklear and out of
/// the hands of the user. From now on users don't have to care
/// about panels unless they care about some information. If you
/// still need the panel just call `nk_window_get_panel`.
/// - 2016/10/21 (1.24.0) - Changed widget border drawing to stroked rectangle from filled
/// rectangle for less overdraw and widget background transparency.
/// - 2016/10/18 (1.23.0) - Added `nk_edit_focus` for manually edit widget focus control.
/// - 2016/09/29 (1.22.7) - Fixed deduction of basic type in non `<stdint.h>` compilation.
/// - 2016/09/29 (1.22.6) - Fixed edit widget UTF-8 text cursor drawing bug.
/// - 2016/09/28 (1.22.5) - Fixed edit widget UTF-8 text appending/inserting/removing.
/// - 2016/09/28 (1.22.4) - Fixed drawing bug inside edit widgets which offset all text
/// text in every edit widget if one of them is scrolled.
/// - 2016/09/28 (1.22.3) - Fixed small bug in edit widgets if not active. The wrong
/// text length is passed. It should have been in bytes but
/// was passed as glyphs.
/// - 2016/09/20 (1.22.2) - Fixed color button size calculation.
/// - 2016/09/20 (1.22.1) - Fixed some `nk_vsnprintf` behavior bugs and removed `<stdio.h>`
/// again from `NK_INCLUDE_STANDARD_VARARGS`.
/// - 2016/09/18 (1.22.0) - C89 does not support vsnprintf only C99 and newer as well
/// as C++11 and newer. In addition to use vsnprintf you have
/// to include <stdio.h>. So just defining `NK_INCLUDE_STD_VAR_ARGS`
/// is not enough. That behavior is now fixed. By default if
/// both varargs as well as stdio is selected I try to use
/// vsnprintf if not possible I will revert to vsprintf. If
/// varargs but not stdio was defined I will use my own function.
/// - 2016/09/15 (1.21.2) - Fixed panel `close` behavior for deeper panel levels.
/// - 2016/09/15 (1.21.1) - Fixed C++ errors and wrong argument to `nk_panel_get_xxxx`.
/// - 2016/09/13 (1.21.0) - !BREAKING! Fixed nonblocking popup behavior in menu, combo,
/// and contextual which prevented closing in y-direction if
/// popup did not reach max height.
/// In addition the height parameter was changed into vec2
/// for width and height to have more control over the popup size.
/// - 2016/09/13 (1.20.3) - Cleaned up and extended type selection.
/// - 2016/09/13 (1.20.2) - Fixed slider behavior hopefully for the last time. This time
/// all calculation are correct so no more hackery.
/// - 2016/09/13 (1.20.1) - Internal change to divide window/panel flags into panel flags and types.
/// Suprisinly spend years in C and still happened to confuse types
/// with flags. Probably something to take note.
/// - 2016/09/08 (1.20.0) - Added additional helper function to make it easier to just
/// take the produced buffers from `nk_convert` and unplug the
/// iteration process from `nk_context`. So now you can
/// just use the vertex,element and command buffer + two pointer
/// inside the command buffer retrieved by calls `nk__draw_begin`
/// and `nk__draw_end` and macro `nk_draw_foreach_bounded`.
/// - 2016/09/08 (1.19.0) - Added additional asserts to make sure every `nk_xxx_begin` call
/// for windows, popups, combobox, menu and contextual is guarded by
/// `if` condition and does not produce false drawing output.
/// - 2016/09/08 (1.18.0) - Changed confusing name for `NK_SYMBOL_RECT_FILLED`, `NK_SYMBOL_RECT`
/// to hopefully easier to understand `NK_SYMBOL_RECT_FILLED` and
/// `NK_SYMBOL_RECT_OUTLINE`.
/// - 2016/09/08 (1.17.0) - Changed confusing name for `NK_SYMBOL_CIRLCE_FILLED`, `NK_SYMBOL_CIRCLE`
/// to hopefully easier to understand `NK_SYMBOL_CIRCLE_FILLED` and
/// `NK_SYMBOL_CIRCLE_OUTLINE`.
/// - 2016/09/08 (1.16.0) - Added additional checks to select correct types if `NK_INCLUDE_FIXED_TYPES`
/// is not defined by supporting the biggest compiler GCC, clang and MSVC.
/// - 2016/09/07 (1.15.3) - Fixed `NK_INCLUDE_COMMAND_USERDATA` define to not cause an error.

/// - 2016/09/03 (1.15.1) - Fixed gaps inside combo boxes in OpenGL.
/// - 2016/09/02 (1.15.0) - Changed nuklear to not have any default vertex layout and
/// instead made it user provided. The range of types to convert
/// to is quite limited at the moment, but I would be more than
/// happy to accept PRs to add additional.
/// - 2016/08/30 (1.14.2) - Removed unused variables.
/// - 2016/08/30 (1.14.1) - Fixed C++ build errors.

/// window was in Read Only Mode.
/// - 2016/08/30 (1.13.1) - Fixed popup panel padding handling which was previously just
/// a hack for combo box and menu.
/// - 2016/08/30 (1.13.0) - Removed `NK_WINDOW_DYNAMIC` flag from public API since
/// it is bugged and causes issues in window selection.
/// - 2016/08/30 (1.12.0) - Removed scaler size. The size of the scaler is now
/// determined by the scrollbar size.
/// - 2016/08/30 (1.11.2) - Fixed some drawing bugs caused by changes from 1.11.0.
/// - 2016/08/30 (1.11.1) - Fixed overlapping minimized window selection.
/// - 2016/08/30 (1.11.0) - Removed some internal complexity and overly complex code

/// - 2016/08/25 (1.10.0) - Changed `nk_input_is_key_pressed` and 'nk_input_is_key_released'

/// - 2016/08/17 (1.09.6) - Removed invalid check for value zero in `nk_propertyx`.
/// - 2016/08/16 (1.09.5) - Fixed ROM mode for deeper levels of popup windows parents.
/// - 2016/08/15 (1.09.4) - Editbox are now still active if enter was pressed with flag
/// `NK_EDIT_SIG_ENTER`. Main reasoning is to be able to keep
/// typing after committing.
/// - 2016/08/15 (1.09.4) - Removed redundant code.
/// - 2016/08/15 (1.09.4) - Fixed negative numbers in `nk_strtoi` and remove unused variable.
/// - 2016/08/15 (1.09.3) - Fixed `NK_WINDOW_BACKGROUND` flag behavior to select a background
/// window only as selected by hovering and not by clicking.

/// hidden and therefore not visible.
/// - 2016/08/12 (1.09.1) - nk_window_is_closed now queries the correct flag `NK_WINDOW_CLOSED`
/// instead of the old flag `NK_WINDOW_HIDDEN`.
/// - 2016/08/09 (1.09.0) - Added additional double version to nk_property and changed
/// the underlying implementation to not cast to float and instead
/// work directly on the given values.
/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
/// floating pointer number to string conversion for additional
/// precision.
/// - 2016/08/09 (1.08.0) - Added additional define to overwrite library internal
/// string to floating point number conversion for additional
/// precision.
/// - 2016/08/08 (1.07.2) - Fixed compiling error without define `NK_INCLUDE_FIXED_TYPE`.
/// - 2016/08/08 (1.07.1) - Fixed possible floating point error inside `nk_widget` leading
/// to wrong widget width calculation which results in widgets falsely
/// becoming tagged as not inside window and cannot be accessed.
/// - 2016/08/08 (1.07.0) - Nuklear now differentiates between hiding a window (NK_WINDOW_HIDDEN) and
/// closing a window (NK_WINDOW_CLOSED). A window can be hidden/shown
/// by using `nk_window_show` and closed by either clicking the close
/// icon in a window or by calling `nk_window_close`. Only closed
/// windows get removed at the end of the frame while hidden windows
/// remain.
/// - 2016/08/08 (1.06.0) - Added `nk_edit_string_zero_terminated` as a second option to

/// - 2016/08/04 (1.04.4) - Fixed fast window scaling behavior.
/// - 2016/08/04 (1.04.3) - Fixed window scaling, movement bug which appears if you
/// move/scale a window and another window is behind it.
/// If you are fast enough then the window behind gets activated
/// and the operation is blocked. I now require activating
/// by hovering only if mouse is not pressed.
/// - 2016/08/04 (1.04.2) - Fixed changing fonts.
/// - 2016/08/03 (1.04.1) - Fixed `NK_WINDOW_BACKGROUND` behavior.

/// - 2016/07/29 (1.03.0) - Moved the window/table pool into the header part to
/// simplify memory management by removing the need to
/// allocate the pool.
/// - 2016/07/29 (1.02.0) - Added auto scrollbar hiding window flag which if enabled
/// will hide the window scrollbar after NK_SCROLLBAR_HIDING_TIMEOUT
/// seconds without window interaction. To make it work
/// you have to also set a delta time inside the `nk_context`.
/// - 2016/07/25 (1.01.1) - Fixed small panel and panel border drawing bugs.
/// - 2016/07/15 (1.01.0) - Added software cursor to `nk_style` and `nk_context`.
