However, consider that OS mouse cursors are typically rendered through a very specific hardware-accelerated

as the mouse, that disconnect may be jarring to particularly sensitive users.
You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor

regularly rendered software cursor.

@ -389,27 +390,27 @@ Long explanation:
- Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame, those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder, we provide functions for popular graphics APIs (OpenGL, DirectX, etc.).
- Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
We carry the information to identify a "texture" in the ImTextureID type.
ImTextureID is nothing more than a void*, aka 4/8 bytes worth of data: just enough to store one pointer or integer of your choice.
ImTextureID default to ImU64 aka 8 bytes worth of data: just enough to store one pointer or integer of your choice.
Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely passes ImTextureID values until they reach your rendering function.
- In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
```cpp
OpenGL:
- ImTextureID = GLuint
- ImTextureID should contains 'GLuint' (GL texture identifier).
- See ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp
```
```cpp
DirectX9:
- ImTextureID = LPDIRECT3DTEXTURE9
- ImTextureID should contain a 'LPDIRECT3DTEXTURE9' (pointer).
- See ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp
```
```cpp
DirectX11:
- ImTextureID = ID3D11ShaderResourceView*
- ImTextureID should contain a 'ID3D11ShaderResourceView*' (pointer)
- See ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp
```
```cpp
DirectX12:
- ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE
- ImTextureID should contain a 'D3D12_GPU_DESCRIPTOR_HANDLE' (always 64-bits)
- See ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp

C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTextureID / void*, and vice-versa.
Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTextureID / void*.
