// dear imgui: Renderer + Platform Backend for Marmalade + IwGx
// Marmalade code: Copyright (C) 2015 by Giovanni Zito (this file is part of Dear ImGui)
// Implemented features:
// [X] Renderer: User texture binding. Use 'CIwTexture*' as ImTextureID. Read the FAQ about ImTextureID!
// Missing features:
// [ ] Renderer: Clipping rectangles are not honored.
// 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)
// 2021-12-08: Renderer: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_Marmalade_RenderDrawData() in the .h file so you can call it yourself.
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

- InputText: made double-click select word, triple-line select line. Word delimitation logic differs
slightly from the one used by CTRL+arrows. (#2244)
- InputText: fixed ReadOnly flag preventing callbacks from receiving the text buffer. (#4762) [@actondev]
- InputText: fixed Shift+Delete from not cutting into clipboard. (#4818, #1541) [@corporateshark]
- InputTextMultiline: fixed incorrect padding when FrameBorder > 0. (#3781, #4794)
- InputTextMultiline: fixed vertical tracking with large values of FramePadding.y. (#3781, #4794)
- Separator: fixed cover all columns while called inside a table. (#4787)

- Clipper: fixed invalid state when number of frozen table row is smaller than ItemCount.
- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceAllowNullID doesn't lose
tooltip when scrolling. (#143)

the IMGUI_USE_WCHAR32 compile-time option. (#4802) [@SlavicPotato]

io.MouseDrawCursor flag is enabled). (#4713) [@nobody-special666]

- Backends: OpenGL2, Allegro5, Marmalade: Fixed mishandling of the ImDrawCmd::IdxOffset field.
This is an old bug, but due to the way we created drawlists, it never had any visible side-effect before.
The new code for handling Modal and CTRL+Tab dimming/whitening recently made the bug surface. (#4790)
- Backends: Win32: Store left/right variants of Ctrl/Shift/Alt mods in KeysDown[] array. (#2625) [@thedmd]
- Backends: DX12: Fixed DRAW_EMPTY_SCISSOR_RECTANGLE warnings. (#4775)
- Backends: SDL_Renderer: Added support for large meshes (64k+ vertices) with 16-bit indices,
enabling 'ImGuiBackendFlags_RendererHasVtxOffset' in the backend. (#3926) [@rokups]
- Backends: SDL_Renderer: Fix for SDL 2.0.19+ RenderGeometryRaw() API signature change. (#4819) [@sridenour]
- Backends: OSX: Generally fix keyboard support. Keyboard arrays indexed using kVK_* codes, e.g.
ImGui::IsKeyPressed(kVK_Space). Don't set mouse cursor shape unconditionally. Handle two fingers scroll
cancel event. (#4759, #4253, #1873) [@stuartcarnie]
