// dear imgui: Platform Backend for GLFW
// This needs to be used along with a Renderer (e.g. OpenGL3, Vulkan, WebGPU..)
// (Info: GLFW is a cross-platform general purpose library for handling windows, inputs, OpenGL/Vulkan graphics context creation, etc.)
// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ for full feature support.)
// Implemented features:
// [X] Platform: Clipboard support.
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
// [x] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
// [X] Platform: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// Issues:
// [ ] Platform: Multi-viewport support: ParentViewportID not honored, and so io.ConfigViewportsNoDefaultParent has no effect (minor).
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// 2024-01-17: Explicitly fill all of WGPUDepthStencilState since standard removed defaults.

// 2023-04-11: Align buffer sizes. Use WGSL shaders instead of precompiled SPIR-V.
// 2023-04-11: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).

// (minor and older changes stripped away, please see git history for details)
// 2024-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
// 2023-09-25: Inputs: Synthesize key-down event on key-up for VK_SNAPSHOT / ImGuiKey_PrintScreen as Windows doesn't emit it (same behavior as GLFW/SDL).
// 2023-09-07: Inputs: Added support for keyboard codepage conversion for when application is compiled in MBCS mode and using a non-Unicode window.
// 2023-04-19: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw Win32/Winapi with OpenGL. (#3218)
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen. (#2702)
// 2023-02-15: Inputs: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse position over non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
// 2023-02-02: Inputs: Flipping WM_MOUSEHWHEEL (horizontal mouse-wheel) value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
// 2022-09-28: Inputs: Convert WM_CHAR values with MultiByteToWideChar() when window class was registered as MBCS (not Unicode).
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).

- 2023/08/20 (0.17) - ImPlotFlags_NoChild was removed as child windows are no longer needed to capture scroll. You can safely remove this flag if you were using it.
- 2023/06/26 (0.15) - Various build fixes related to updates in Dear ImGui internals.
- 2022/11/25 (0.15) - Make PlotText honor ImPlotItemFlags_NoFit.
- 2022/06/19 (0.14) - The signature of ColormapScale has changed to accommodate a new ImPlotColormapScaleFlags parameter
- 2022/06/17 (0.14) - **IMPORTANT** All PlotX functions now take an ImPlotX_Flags `flags` parameter. Where applicable, it is located before the existing `offset` and `stride` parameters.
If you were providing offset and stride values, you will need to update your function call to include a `flags` value. If you fail to do this, you will likely see

Str
Simple C++ string type with an optional local buffer, by Omar Cornut
https://github.com/ocornut/str
LICENSE
This software is in the public domain. Where that dedication is not
recognized, you are granted a perpetual, irrevocable license to copy,
distribute, and modify this file as you see fit.
USAGE
Include Str.h in whatever places need to refer to it.
In ONE .cpp file, write '#define STR_IMPLEMENTATION' before the #include.
This expands out the actual implementation into that C/C++ file.
NOTES
- This isn't a fully featured string class.
- It is a simple, bearable replacement to std::string that isn't heap abusive nor bloated (can actually be debugged by humans!).
- String are mutable. We don't maintain size so length() is not-constant time.
- Maximum string size currently limited to 2 MB (we allocate 21 bits to hold capacity).
- Local buffer size is currently limited to 1023 bytes (we allocate 10 bits to hold local buffer size).
- We could easily raise those limits if we are ok to increase the structure overhead in 32-bits mode.
- In "non-owned" mode for literals/reference we don't do any tracking/counting of references.
- Overhead is 8-bytes in 32-bits, 16-bytes in 64-bits (12 + alignment).
- I'm using this code but it hasn't been tested thoroughly.
The idea is that you can provide an arbitrary sized local buffer if you expect string to fit
most of the time, and then you avoid using costly heap.
No local buffer, always use heap, sizeof()==8~16 (depends if your pointers are 32-bits or 64-bits)
Str s = "hey"; // use heap
With a local buffer of 16 bytes, sizeof() == 8~16 + 16 bytes.
Str16 s = "filename.h"; // copy into local buffer
Str16 s = "long_filename_not_very_long_but_longer_than_expected.h"; // use heap
With a local buffer of 256 bytes, sizeof() == 8~16 + 256 bytes.
Str256 s = "long_filename_not_very_long_but_longer_than_expected.h"; // copy into local buffer
Common sizes are defined at the bottom of Str.h, you may define your own.
Functions:
Str256 s;
s.set("hello sailor"); // set (copy)
s.setf("%s/%s.tmp", folder, filename); // set (w/format)
s.append("hello"); // append. cost a length() calculation!
s.appendf("hello %d", 42); // append (w/format). cost a length() calculation!
s.set_ref("Hey!"); // set (literal/reference, just copy pointer, no tracking)
Constructor helper for format string: add a trailing 'f' to the type. Underlying type is the same.
Str256f filename("%s/%s.tmp", folder, filename); // construct (w/format)
fopen(Str256f("%s/%s.tmp, folder, filename).c_str(), "rb"); // construct (w/format), use as function param, destruct
Constructor helper for reference/literal:
StrRef ref("literal"); // copy pointer, no allocation, no string copy
StrRef ref2(GetDebugName()); // copy pointer. no tracking of anything whatsoever, know what you are doing!
All StrXXX types derives from Str and instance hold the local buffer capacity.
So you can pass e.g. Str256* to a function taking base type Str* and it will be functional!
void MyFunc(Str& s) { s = "Hello"; } // will use local buffer if available in Str instance
(Using a template e.g. Str<N> we could remove the LocalBufSize storage but it would make passing typed Str<> to functions tricky.
Instead we don't use template so you can pass them around as the base type Str*. Also, templates are ugly.)

- This isn't a fully featured string class.
- It is a simple, bearable replacement to std::string that isn't heap abusive nor bloated (can actually be debugged by humans).
- String are mutable. We don't maintain size so length() is not-constant time.
- Maximum string size currently limited to 2 MB (we allocate 21 bits to hold capacity).
- Local buffer size is currently limited to 1023 bytes (we allocate 10 bits to hold local buffer size).
- In "non-owned" mode for literals/reference we don't do any tracking/counting of references.
- Overhead is 8-bytes in 32-bits, 16-bytes in 64-bits (12 + alignment).
- This code hasn't been tested very much. it is probably incomplete or broken. Made it for my own use.
The idea is that you can provide an arbitrary sized local buffer if you expect string to fit
most of the time, and then you avoid using costly heap.
No local buffer, always use heap, sizeof()==8~16 (depends if your pointers are 32-bits or 64-bits)
Str s = "hey";
With a local buffer of 16 bytes, sizeof() == 8~16 + 16 bytes.
Str16 s = "filename.h"; // copy into local buffer
Str16 s = "long_filename_not_very_long_but_longer_than_expected.h"; // use heap
With a local buffer of 256 bytes, sizeof() == 8~16 + 256 bytes.
Str256 s = "long_filename_not_very_long_but_longer_than_expected.h"; // copy into local buffer
Common sizes are defined at the bottom of Str.h, you may define your own.
Functions:
Str256 s;
s.set("hello sailor"); // set (copy)
s.setf("%s/%s.tmp", folder, filename); // set (w/format)
s.append("hello"); // append. cost a length() calculation!
s.appendf("hello %d", 42); // append (w/format). cost a length() calculation!
s.set_ref("Hey!"); // set (literal/reference, just copy pointer, no tracking)
Constructor helper for format string: add a trailing 'f' to the type. Underlying type is the same.
Str256f filename("%s/%s.tmp", folder, filename); // construct (w/format)
fopen(Str256f("%s/%s.tmp, folder, filename).c_str(), "rb"); // construct (w/format), use as function param, destruct
Constructor helper for reference/literal:
StrRef ref("literal"); // copy pointer, no allocation, no string copy
StrRef ref2(GetDebugName()); // copy pointer. no tracking of anything whatsoever, know what you are doing!
All StrXXX types derives from Str and instance hold the local buffer capacity. So you can pass e.g. Str256* to a function taking base type Str* and it will be functional.

/*
CHANGELOG
0.32 - added owned() accessor.
0.31 - fixed various warnings.
0.30 - turned into a single header file, removed Str.cpp.
0.29 - fixed bug when calling reserve on non-owned strings (ie. when using StrRef or set_ref), and fixed <string> include.
0.28 - breaking change: replaced Str32 by Str30 to avoid collision with Str32 from MacTypes.h .
0.27 - added STR_API and basic .natvis file.
0.26 - fixed set(cont char* src, const char* src_end) writing null terminator to the wrong position.
0.25 - allow set(const char* NULL) or operator= NULL to clear the string. note that set() from range or other types are not allowed.
0.24 - allow set_ref(const char* NULL) to clear the string. include fixes for linux.
0.23 - added append(char). added append_from(int idx, XXX) functions. fixed some compilers warnings.
0.22 - documentation improvements, comments. fixes for some compilers.
0.21 - added StrXXXf() constructor to construct directly from a format string.
*/
/*
TODO
- Since we lose 4-bytes of padding on 64-bits architecture, perhaps just spread the header to 8-bytes and lift size limits?
- More functions/helpers.
