// Verify ABI compatibility between caller code and compiled version of Dear ImGui. This helps detects some build issues.
// Called by IMGUI_CHECKVERSION().
// Verify that the type sizes are matching between the calling file's compilation unit and imgui.cpp's compilation unit
// If this triggers you have mismatched headers and compiled code versions.
// - It could be because of a build issue (using new headers with old compiled code)
