Headlessly creates a new vulkan instance, with conditional MacOS
support, and enables the `VK_EXT_debug_utils` instance-extension with a
debug-messenger to hook onto validation layer messages.
A lot of the architecture of the emulator here does not allow for vulkan
to initialize easily since it involves a bit of data to be exchanged
between SDL and Vulkan. This commit just adds the foundational linkage
and library code for vulkan support.
Rather than declaring a big C++ literal for these strings, they are now
proper `.vert` and `.frag` files that will become embedded into the
application at build-time. It also allows for clang-format to format the
glsl files the same as our C++ code. CMake will also automatically track
and re-embed the file if it detects that the glsl source files have
changed since the last build. Ex, making a change to
`opengl_display.frag` and compiling will automatically recompile and
link the resource-target that it is associated with.
Allows the OpenGL backend to be fully disabled, continuing a modular
pattern of having multiple possible rendering backends. Also defines the
`ENABLE_OPENGL` preprocessor in the case of conditional source-file
changes depending on the rendering backend.
Rather than having the entire implementation within `emulator.cpp`,
causing incremental builds to be much slower, give it its own
translation unit `stb_image_write.c`.
We loads keys from AppData/Alber/sysdata/aes_keys.txt.
NOTE: We do differ from other emulators by not hardcoding the generator key, it's the user responsibility to provide it in aes_keys.txt.
Adds a project-wide setting for allowing renderer code to add additional
diagnostic data. Currently used to allow `opengl.hpp` to conditionally
implement debug-labeling and scopes.
Makes the implementation of `IOFile` private, allowing inclusions and
defines such as `#define fseeko` and `#include <io.h>` to not poison
client-code or the global namespace.
