- moved slang shaders to spvshaders to separate software and hardware
shaders
- split Makefile.am into Makefile.am, src/Makefile.am and
src/spvshaders/Makefile.am
- build shaders as DATA primary, instead of both PROGRAMS and SCRIPTS,
which greatly simplifies building. Before that, we had to first build
them as PROGRAMS, and then copy them as SCRIPTS to remove executable
extensions (i.e. ".exe" for Windows)
- changed final executable dir from enginedir to bindir, which makes
automake see it as an exec instead of data
- compute relative paths from C++, which makes it possible to change
dirs arbitrarily when running make while still having a relocatable
executable
- updated README.md to reflect changes in dirs
- use AX_COMPARE_VERSION() to simplify checking if Vulkan headers
version is correct
- factored out most of paths computation in engine::path_utils::Paths

Makefile.am is too ugly, but I don't have a better solution right now.
- fused Makefile.am and src/Makefile.am
- adding back windows cross-compilation
- improved README.md a lot
- added configure option to enable debug, which greatly simplifies
development when writing shaders
- removed dependency on LunarG's Vulkan SDK by having dependency only on
Vulkan headers, library and slangc
- removed print C++ header because I have an old MinGW which doesn't
support it. It will be restored in the future
- make every assets path relative to be able to build anywhere and run
elsewhere
- moved stb_image.h inside source directory instead of making it a
dependency, which is more aligned with stb philosophy
- moved assets inside source code to make it easy to compile and run the
engine
- improved configure.ac by checking Vulkan headers version directly in
the configure script instead of within C code, which allows us to also
do theses checks when cross-compiling

This commit add mipmaps, but for now, mipmaps are generated on the gpu
at runtime. We should generate them in advance.
- added mipmaps for the hardware renderer
- renamed stb_image.c to stb_image.cpp
- add compiler flag to stb_image.cpp to prevent warning
- added pipe notation for various objects to have all clipping functions
be left to right. We need this for the time being because dot notation
would considerably complicate the current implementation
- small improvements

There is still a lot of work needed to refactor it properly.
- use the Sutherland–Hodgman algorithm, with some minor changes
- made clipping more general, allowing clipping of any coordinate,
before and after division by w
- compute the z coordinate only at the fragment stage instead of each
time clipping creates / moves a vertex, in addition to the fragment
stage
- added VectorCoords to choose at compile-time different coordinates
based on a template argument
- added transpose struct to allow shuffling of vectors coordinates
- added math::utils::lerp which interpolate linearly a float
- added Vector{2,3,4}::map() which maps a vector from one range to
another
- added template parameter to DerivedVertex (and therefore
TriangleDerived) to allow choosing which dimension to use

- removed "using" directive in .hpp
- reverse order of arguments for quaternion rotation, i.e. q.rot(v)
instead of v.rot(q), where q is a quaterinon and v a vector
- pass the inverse of the view matrix to render_and_present_frame, to
allow light calculation in shaders (we used to just pass the matrix of
the quaternion of the transformation, i.e. discard scaling and
translations)
- added another mesh and texture (viking_room) for testing purposes
- added transparent background option
- added Quaternion::look_towards(), which is the equivalent of
Matrix4::look_at() but only for rotations
- various improvement to .obj parsing
- load texture coordinates from .obj file
- merged duplicate vertices in Mesh::linearize_indices()

- wait idle on present queue instead of graphics queue
- assume only one bit of VkDebugUtilsMessageSeverityFlagBitsEXT is set;
it seems to be always the case
- rename every _create_info to _ci
- print less debug information, by reducing debug output to warning and
up, and by removing printing of all of devices properties
- make as much blocks and lambdas as possible to contain every variable
to a small scope
- use designator lists everywhere
- rename device to physical_device, and logical_device to device
