+-mod range;
+//! ThinVec is exactly the same as Vec, except that it stores its `len` and `capacity` in the buffer
+//! it allocates.
+//!
+//! This makes the memory footprint of ThinVecs lower; notably in cases where space is reserved for
+//! a non-existence ThinVec<T>. So `Vec<ThinVec<T>>` and `Option<ThinVec<T>>::None` will waste less
+//! space. Being pointer-sized also means it can be passed/stored in registers.
+//!
+//! Of course, any actually constructed ThinVec will theoretically have a bigger allocation, but
+//! the fuzzy nature of allocators means that might not actually be the case.
+//!
+//! Properties of Vec that are preserved:
+//! * `ThinVec::new()` doesn't allocate (it points to a statically allocated singleton)
+//! * reallocation can be done in place
+//! * `size_of::<ThinVec<T>>()` == `size_of::<Option<ThinVec<T>>>()`
+//!
+//! Properties of Vec that aren't preserved:
+//! * `ThinVec<T>` can't ever be zero-cost roundtripped to a `Box<[T]>`, `String`, or `*mut T`
+//! * `from_raw_parts` doesn't exist
+//! * ThinVec currently doesn't bother to not-allocate for Zero Sized Types (e.g. `ThinVec<()>`),
+//!   but it could be done if someone cared enough to implement it.
+//!
+//!
+//!
+//! # Gecko FFI
+//!
+//! If you enable the gecko-ffi feature, ThinVec will verbatim bridge with the nsTArray type in
+//! Gecko (Firefox). That is, ThinVec and nsTArray have identical layouts *but not ABIs*, 
+//! so nsTArrays/ThinVecs an be natively manipulated by C++ and Rust, and ownership can be 
+//! transferred across the FFI boundary (**IF YOU ARE CAREFUL, SEE BELOW!!**).
+//!
+//! While this feature is handy, it is also inherently dangerous to use because Rust and C++ do not
+//! know about eachother. Specifically, this can be an issue with non-POD types (types which
+//! have destructors, move constructors, or are `!Copy`).
+//!
+//! ## Do Not Pass By Value
+//!
+//! The biggest thing to keep in mind is that **FFI functions cannot pass ThinVec/nsTArray 
+//! by-value**. That is, these are busted APIs:
+//!
+//! ```rust,ignore
+//! // BAD WRONG
+//! extern fn process_data(data: ThinVec<u32>) { ... }
+//! // BAD WRONG
+//! extern fn get_data() -> ThinVec<u32> { ... }
+//! ```
+//!
+//! You must instead pass by-reference:
+//!
+//! ```rust
+//! # use thin_vec::*;
+//! # use std::mem;
+//!
+//! // Read-only access, ok!
+//! extern fn process_data(data: &ThinVec<u32>) {
+//!     for val in data {
+//!         println!("{}", val);
+//!     }
+//! }
+//! 
+//! // Replace with empty instance to take ownership, ok!
+//! extern fn consume_data(data: &mut ThinVec<u32>) {
+//!     let owned = mem::replace(data, ThinVec::new());
+//!     mem::drop(owned);
+//! }
+//! 
+//! // Mutate input, ok!
+//! extern fn add_data(dataset: &mut ThinVec<u32>) {
+//!     dataset.push(37);
+//!     dataset.push(12);
+//! }
+//! 
+//! // Return via out-param, usually ok!
+//! //
+//! // WARNING: output must be initialized! (Empty nsTArrays are free, so just do it!)
+//! extern fn get_data(output: &mut ThinVec<u32>) {
+//!     *output = thin_vec![1, 2, 3, 4, 5];
+//! }
+//! ```
+//!
+//! Ignorable Explanation For Those Who Really Want To Know Why:
+//!
+//! > The fundamental issue is that Rust and C++ can't currently communicate about destructors, and
+//! > the semantics of C++ require destructors of function arguments to be run when the function
+//! > returns. Whether the callee or caller is responsible for this is also platform-specific, so
+//! > trying to hack around it manually would be messy. 
+//! >
+//! > Also a type having a destructor changes its C++ ABI, because that type must actually exist 
+//! > in memory (unlike a trivial struct, which is often passed in registers). We don't currently
+//! > have a way to communicate to Rust that this is happening, so even if we worked out the
+//! > destructor issue with say, MaybeUninit, it would still be a non-starter without some RFCs
+//! > to add explicit rustc support.
+//! >
+//! > Realistically, the best answer here is to have a "heavier" bindgen that can secretly
+//! > generate FFI glue so we can pass things "by value" and have it generate by-reference code
+//! > behind our back (like the cxx crate does). This would muddy up debugging/searchfox though.
+//!
+//! ## Types Should Be Trivially Relocatable
+//!
+//! Types in Rust are always trivially relocatable (unless suitably borrowed/[pinned][]/hidden).
+//! This means all Rust types are legal to relocate with a bitwise copy, you cannot provide
+//! copy or move constructors to execute when this happens, and the old location won't have its
+//! destructor run. This will cause problems for types which have a significant location
+//! (types that intrusively point into themselves or have their location registered with a service).
+//!
+//! While relocations are generally predictable if you're very careful, **you should avoid using
+//! types with significant locations with Rust FFI**.
+//!
+//! Specifically, ThinVec will trivially relocate its contents whenever it needs to reallocate its
+//! buffer to change its capacity. This is the default reallocation strategy for nsTArray, and is
+//! suitable for the vast majority of types. Just be aware of this limitation!
+//!
+//! ## Auto Arrays Are Dangerous
+//!
+//! ThinVec has *some* support for handling auto arrays which store their buffer on the stack, 
+//! but this isn't well tested.
+//!
+//! Regardless of how much support we provide, Rust won't be aware of the buffer's limited lifetime,
+//! so standard auto array safety caveats apply about returning/storing them! ThinVec won't ever
+//! produce an auto array on its own, so this is only an issue for transferring an nsTArray into
+//! Rust.
+//!
+//! ## Other Issues
+//!
+//! Standard FFI caveats also apply: 
+//!
+//!  * Rust is more strict about POD types being initialized (use MaybeUninit if you must)
+//!  * `ThinVec<T>` has no idea if the C++ version of `T` has move/copy/assign/delete overloads
+//!  * `nsTArray<T>` has no idea if the Rust version of `T` has a Drop/Clone impl
+//!  * C++ can do all sorts of unsound things that Rust can't catch
+//!  * C++ and Rust don't agree on how zero-sized/empty types should be handled
+//!
+//! The gecko-ffi feature will not work if you aren't linking with code that has nsTArray
+//! defined. Specifically, we must share the symbol for nsTArray's empty singleton. You will get
+//! linking errors if that isn't defined.
+//!
+//! The gecko-ffi feature also limits ThinVec to the legacy behaviors of nsTArray. Most notably,
+//! nsTArray has a maximum capacity of i32::MAX (~2.1 billion items). Probably not an issue.
+//! Probably.

+Skia does not support big endian. The places to fix are too numerous and upstream (skia, not Mozilla)
+has no interest in maintaining big endian.
+So here we try to swizzle the input for skia, so that skia always works on LE, and when it comes
+out again, we transform back to BE.

+Problem description: Tab-titles that are too long to fit into a tab get faded out.
+                     On big endian this is broken and instead of fading out, the 
+                     tab gets white and the font transparent, leading to an unreadable
+                     tab-title
+Solution: This is not a real solution, but a hack. The real solution would have been
+          to byte-swap the correct buffer, but I could not find it.
+          So the next best thing is to deactivate the fading-effect. Now all tab-titles
+          are readable, albeit not as pretty to look at as they could be. 
+Side-effects: I have not yet found an unwanted side-effect.

+commit 0b91f8a668201fc58fa732b8acc496caedfdbae0
+Author: Florian Weimer <fw@deneb.enyo.de>
+Date:   Sun Apr 29 12:18:33 2018 -0700
+
+    Indicate that _PyGC_Head is only 8-byte aligned. (closes bpo-33374)
+
+    By spec, the "long double" in _PyGC_Head requires the union to always be 16-byte
+    aligned. However, obmalloc only yields 8-byte alignment. Compilers including GCC
+    8 are starting to use alignment information to do store-merging. So, the "long
+    double" needs to be changed to a simple "double" as was long ago done in Python
+    3 by e348c8d154cf6342c79d627ebfe89dfe9de23817. For 2.7, we need to add some
+    dummy padding to make sure _PyGC_Head stays the same size.
