Authored by Claude (Opus 4.8): Fix function-item-cast-to-integer warn… - #87

Conversation
…ings A recent rustc change added the `function_casts_as_integer` lint, which warns when a named function item is cast directly to an integer. The d3d9/d3d11 hooking code does this to compare addresses (detecting whether a vtable slot already points at our hook function to avoid double-hooking). Route the function-item operand through a pointer first (`hook_fn as *const () as usize`), as suggested by the compiler. The numeric address is identical, so all the "already hooked?" comparisons behave exactly as before. Only the function-item operands are changed; the function-pointer operands (vtable fields / stored real fn pointers) do not trigger the lint and are left untouched.
