// Plot and Item Styling
//-----------------------------------------------------------------------------
// Styling colors in ImPlot works similarly to styling colors in ImGui, but
// with one important difference. Like ImGui, all style colors are stored in an
// indexable array in ImPlotStyle. You can permanently modify these values through
// GetStyle().Colors, or temporarily modify them with Push/Pop functions below.
// However, by default all style colors in ImPlot default to a special color
// IMPLOT_AUTO_COL. The behavior of this color depends upon the style color to
// which it as applied:
//
// 1) For style colors associated with plot items (e.g. ImPlotCol_Line),
// IMPLOT_AUTO_COL tells ImPlot to color the item with the next unused
// color in the current colormap. Thus, every item will have a different
// color up to the number of colors in the colormap, at which point the
// colormap will roll over. For most use cases, you should not need to
// set these style colors to anything but IMPLOT_COL_AUTO; you are
// probably better off changing the current colormap. However, if you
// need to explicitly color a particular item you may either Push/Pop
// the style color around the item in question, or use the SetNextXXXStyle
// API below. If you permanently set one of these style colors to a specific
// color, or forget to call Pop, then all subsequent items will be styled
// with the color you set.
//
// 2) For style colors associated with plot styling (e.g. ImPlotCol_PlotBg),
// IMPLOT_AUTO_COL tells ImPlot to set that color from color data in your
// **ImGuiStyle**. The ImGuiCol_ that these style colors default to are
// detailed above, and in general have been mapped to produce plots visually
// consistent with your current ImGui style. Of course, you are free to
// manually set these colors to whatever you like, and further can Push/Pop
// them around individual plots for plot-specific styling (e.g. coloring axes).

// dear imgui: wrapper to use FreeType (instead of stb_truetype)
// Get latest version at https://github.com/ocornut/imgui/tree/master/misc/freetype
// Original code by @vuhdo (Aleksei Skriabin). Improvements by @mikesart. Maintained and v0.60+ by @ocornut.
// dear imgui: FreeType font builder (used as a replacement for the stb_truetype builder)
// (code)
// Changelog:
// - v0.50: (2017/08/16) imported from https://github.com/Vuhdo/imgui_freetype into http://www.github.com/ocornut/imgui_club, updated for latest changes in ImFontAtlas, minor tweaks.
// - v0.51: (2017/08/26) cleanup, optimizations, support for ImFontConfig::RasterizerFlags, ImFontConfig::RasterizerMultiply.
// - v0.52: (2017/09/26) fixes for imgui internal changes.
// - v0.53: (2017/10/22) minor inconsequential change to match change in master (removed an unnecessary statement).
// - v0.54: (2018/01/22) fix for addition of ImFontAtlas::TexUvscale member.
// - v0.55: (2018/02/04) moved to main imgui repository (away from http://www.github.com/ocornut/imgui_club)
// - v0.56: (2018/06/08) added support for ImFontConfig::GlyphMinAdvanceX, GlyphMaxAdvanceX.
// - v0.60: (2019/01/10) re-factored to match big update in STB builder. fixed texture height waste. fixed redundant glyphs when merging. support for glyph padding.
// - v0.61: (2019/01/15) added support for imgui allocators + added FreeType only override function SetAllocatorFunctions().
// - v0.62: (2019/02/09) added RasterizerFlags::Monochrome flag to disable font anti-aliasing (combine with ::MonoHinting for best results!)
// - v0.63: (2020/06/04) fix for rare case where FT_Get_Char_Index() succeed but FT_Load_Glyph() fails.
// Get the latest version at https://github.com/ocornut/imgui/tree/master/misc/freetype
// Original code by @vuhdo (Aleksei Skriabin). Improvements by @mikesart. Maintained since 2019 by @ocornut.
// Gamma Correct Blending:
// FreeType assumes blending in linear space rather than gamma space.
// See https://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html#FT_Render_Glyph
// For correct results you need to be using sRGB and convert to linear space in the pixel shader output.
// The default imgui styles will be impacted by this change (alpha values will need tweaking).
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2021/03/05: added ImGuiFreeTypeBuilderFlags_Bitmap to load bitmap glyphs.
// 2021/03/02: set 'atlas->TexPixelsUseColors = true' to help some backends with deciding of a prefered texture format.
// 2021/01/28: added support for color-layered glyphs via ImGuiFreeTypeBuilderFlags_LoadColor (require Freetype 2.10+).
// 2021/01/26: simplified integration by using '#define IMGUI_ENABLE_FREETYPE'.
// renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. removed ImGuiFreeType::BuildFontAtlas().
// 2020/06/04: fix for rare case where FT_Get_Char_Index() succeed but FT_Load_Glyph() fails.
// 2019/02/09: added RasterizerFlags::Monochrome flag to disable font anti-aliasing (combine with ::MonoHinting for best results!)

// About Gamma Correct Blending:
// - FreeType assumes blending in linear space rather than gamma space.
// - See https://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html#FT_Render_Glyph
// - For correct results you need to be using sRGB and convert to linear space in the pixel shader output.
// - The default dear imgui styles will be impacted by this change (alpha values will need tweaking).
// FIXME: cfg.OversampleH, OversampleV are not supported (but perhaps not so necessary with this rasterizer).

// 2021-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().

// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).

// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.

// You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
// Read online: https://github.com/ocornut/imgui/tree/master/docs
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2021-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2021-08-19: OpenGL: Embed and use our own minimal GL loader (imgui_impl_opengl3_loader.h), removing requirement and support for third-party loader.
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
// 2021-06-25: OpenGL: Use OES_vertex_array extension on Emscripten + backup/restore current state.
// 2021-06-21: OpenGL: Destroy individual vertex/fragment shader objects right after they are linked into the main shader.
// 2021-05-24: OpenGL: Access GL_CLIP_ORIGIN when "GL_ARB_clip_control" extension is detected, inside of just OpenGL 4.5 version.
// 2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
// 2021-04-06: OpenGL: Don't try to read GL_CLIP_ORIGIN unless we're OpenGL 4.5 or greater.
// 2021-02-18: OpenGL: Change blending equation to preserve alpha in output buffer.
// 2021-01-03: OpenGL: Backup, setup and restore GL_STENCIL_TEST state.
// 2020-10-23: OpenGL: Backup, setup and restore GL_PRIMITIVE_RESTART state.
// 2020-10-15: OpenGL: Use glGetString(GL_VERSION) instead of glGetIntegerv(GL_MAJOR_VERSION, ...) when the later returns zero (e.g. Desktop GL 2.x)
