code-style: misc changes (#374)
* ensure static variables comes after non-static ones * remove depreciated DATA32 type * prefer `sizeof(expression)` over `sizeof(Type)`. * silence a -Wsign warning * {gif,webp} loader: use a pointer to reduce code-noise * gif loader: allocate in one place Reviewed-on: https://codeberg.org/nsxiv/nsxiv/pulls/374 Reviewed-by: TAAPArthur <taaparthur@noreply.codeberg.org>
