-// Important: to compile on 32-bit systems, the DirectX12 backend requires code to be compiled with '#define ImTextureID ImU64'.
-// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
-// This define is set in the example .vcxproj file and need to be replicated in your app or by adding it to your imconfig.h file.
