// Breadcrumb markers are useful for debugging GPU crashes (i.e. DEVICE_LOST). Internally
// they're just an uint32_t to "tag" a GPU command. These are only used for debugging and do not
// (or at least shouldn't) alter the execution behavior in any way.
//
// When a GPU crashes and Godot was built in dev or debug mode; Godot will dump what commands
// were being executed and what tag they were marked with.
// This makes narrowing down the cause of a crash easier. Note that a GPU can be executing
// multiple commands at the same time. It is also useful to identify data hazards.
//
// For example if each LIGHTMAPPER_PASS must be executed in sequential order, but dumps
// indicated that pass (LIGHTMAPPER_PASS | 5) was being executed at the same time as
// (LIGHTMAPPER_PASS | 4), that would indicate there is a missing barrier or a render graph bug.
//
// The enums are bitshifted by 16 bits so it's possible to add user data via bitwise operations.
// Using this enum is not mandatory; but it is recommended so that all subsystems agree what each
