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. /// - 2017/06/06 (1.38.5) - Fixed `nk_convert` return flag for command buffer. /// - 2017/05/23 (1.38.4) - Fixed activation behavior for widgets partially clipped. /// - 2017/05/10 (1.38.3) - Fixed wrong min window size mouse scaling over boundaries. /// - 2017/05/09 (1.38.2) - Fixed vertical scrollbar drawing with not enough space. /// - 2017/05/09 (1.38.1) - Fixed scaler dragging behavior if window size hits minimum size. /// - 2017/05/06 (1.38.0) - Added platform double-click support. /// - 2017/04/20 (1.37.1) - Fixed key repeat found inside glfw demo backends. /// - 2017/04/20 (1.37.0) - Extended properties with selection and clipboard support. /// - 2017/04/20 (1.36.2) - Fixed #405 overlapping rows with zero padding and spacing. /// - 2017/04/09 (1.36.1) - Fixed #403 with another widget float error. /// - 2017/04/09 (1.36.0) - Added window `NK_WINDOW_NO_INPUT` and `NK_WINDOW_NOT_INTERACTIVE` flags. /// - 2017/04/09 (1.35.3) - Fixed buffer heap corruption. /// - 2017/03/25 (1.35.2) - Fixed popup overlapping for `NK_WINDOW_BACKGROUND` windows. /// - 2017/03/25 (1.35.1) - Fixed windows closing behavior. /// - 2017/03/18 (1.35.0) - Added horizontal scroll requested in #377. /// - 2017/03/18 (1.34.3) - Fixed long window header titles. /// - 2017/03/04 (1.34.2) - Fixed text edit filtering. /// - 2017/03/04 (1.34.1) - Fixed group closable flag. /// - 2017/02/25 (1.34.0) - Added custom draw command for better language binding support. /// - 2017/01/24 (1.33.0) - Added programmatic way to remove edit focus. /// - 2017/01/24 (1.32.3) - Fixed wrong define for basic type definitions for windows. /// - 2017/01/21 (1.32.2) - Fixed input capture from hidden or closed windows. /// - 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 (1.30.0) - Extended scrollbar offset from 16-bit to 32-bit. /// - 2016/12/31 (1.29.2) - Fixed closing window bug of minimized windows. /// - 2016/12/03 (1.29.1) - Fixed wrapped text with no seperator and C89 error. /// - 2016/12/03 (1.29.0) - Changed text wrapping to process words not characters. /// - 2016/11/22 (1.28.6) - Fixed window minimized closing bug. /// - 2016/11/19 (1.28.5) - Fixed abstract combo box closing behavior. /// - 2016/11/19 (1.28.4) - Fixed tooltip flickering. /// - 2016/11/19 (1.28.3) - Fixed memory leak caused by popup repeated closing. /// - 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.

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 `` /// 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 . 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!

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. /// - 2016/09/04 (1.15.2) - Fixed wrong combobox height calculation. /// - 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. /// - 2016/08/30 (1.14.0) - Removed mouse dragging from SDL demo since it does not work correctly. /// - 2016/08/30 (1.13.4) - Tweaked some default styling variables. /// - 2016/08/30 (1.13.3) - Hopefully fixed drawing bug in slider, in general I would /// refrain from using slider with a big number of steps. /// - 2016/08/30 (1.13.2) - Fixed close and minimize button which would fire even if the /// 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.
