Tcod

Added
- New `TCODImage::getSize()` overload which returns a value instead of taking output references.
- New `TCODColor::genMap` overload which supports constexpr.
- `TCODZip` has new `get` and `put` functions with their supported types as overloads.
This includes some types from the new API and C++ types such as `std::optional<std::string>` as an alternative to getting a char pointer.
- `TCODZip` can now load and save paths using `<filesystem>` types.
- Added `tcod::ImagePtr`.
- Added functions to manually set context pixel-to-tile conversions in cases where it can't be set automatically.
- New overloads to `TCODBsp` which can take function callbacks directly.

Changed
- `TCODRandom` is now a movable, non-copyable object.
- `TCODConsole` can now be default constructed.

Fixed
- Constructing `TCODConsole` from `tcod::ConsolePtr` no longer causes a bad free.
- Memory leak when loading images with `TCODZip`.
- Memory leak with tileset atlases belonging to contexts.

Changed
- Code Page 437: Character 0x7F is now assigned to 0x2302 (HOUSE).
[134](https://github.com/libtcod/libtcod/pull/134)
- ``TCOD_RENDERER_GLSL``, ``TCOD_RENDERER_OPENGL``, ``TCOD_RENDERER_SDL``, and ``TCOD_RENDERER_OPENGL2`` now alias to the ``TCOD_RENDERER_SDL2`` renderer.
[137](https://github.com/libtcod/libtcod/pull/137)

Deprecated
- All color constants have been deprecated.

Fixed
- Forced all renderers to ``TCOD_RENDERER_SDL2`` to fix rare graphical artifacts with OpenGL.

[83](https://github.com/libtcod/libtcod/issues/83)

Removed
- Removed GLAD dependencies.

Added
- Added new C print functions: ``TCOD_printf_rgb``, ``TCOD_printn_rgb``, and ``TCOD_vprintf_rgb``.
[133](https://github.com/libtcod/libtcod/pull/133)
- Added a default constructor for ``TCODImage``.

Fixed
- Functions getting the size of an image now handle null pointers consistently.
- Will no longer try to include ``<utf8proc.h>`` when Unicode support is disabled.

Added
- Libtcod can now be built without utf8proc by passing the `-LIBTCOD_UTF8PROC=disable` flag to CMake.

Fixed
- Fixed double present bug in non-context flush functions.
This was affecting performance and also caused a screen flicker whenever the global fade color was active.

Fixed
- Libtcod was not linking `utf8proc` correctly in projects statically built with CMake.

Fixed
- Fix regression in TCODList when items are removed during iteration.
