Use raii-like mechanism to delete resources when not in use.
Fix several issues reported by validation layers (vtennis rtt, main
buffer size resizing, ...)
* cmake: use c++17
* Use std::size
* Use std::make_unique
* Use std::clamp
* Use structured binding
* Use [[fallthrough]]
* Use enable_if_t/is_enum_v/is_integral_v/is_same_v
* Use if constexpr
* Use try_emplace
* Use auto for iterators
* Use inline variables
Use FB_R_CTRL.vclk_div to detect progressive mode.
transform_matrix: Support non-4:3 aspect ratio such as 640x240. Don't
expect 480 height. Issue #690
Add black bars at top and bottom if screen aspect ratio is too low.
Issue #584.
Framebuffer size doesn't depend on screen stretching. Stretching is done
when blitting to screen.
lr: correct subsequent stretching when drawing vmus and xhair
Store FT_W_SOF1 and FT_W_CTRL in render context since they can be
modified before render end. New tentative fix for vf4 water reflection
flashing black during netplay.
Refactor texture cache to use constructors. RTT code moved from
renderers.
Partial revert of ddcd3861d3
dx11: shadow scale factor inverted in per-pixel
vulkan: clear deleted overlay images when terminating
Use color struct for FOG_COL_VERT, FOG_COL_RAM, FOG_CLAMP_MIN,
FOG_CLAMP_MAX and VO_BORDER_COL. Avoid code duplication in renderers.
oit: skip to new frame even if previous frame was never presented
libretro: quad pipeline used for overlay must use subpass 2 in per-pixel
overlay: delay destruction of VMUs images
libretro: WaitIdle on queue instead of wait_sync_index
Refactor imgui backend code into imgui drivers for gl, vk, dx9
Generic GraphicsContext interface for gl/vk/dx9 contexts
Simplify graphics api switching code
dx9, gl(sdl): set swap interval based on monitor refresh rate.
gl: strech direct fb texture based on stretching and rotation
Fix lighgun coords when stretching and/or rotating
Dimension render size based on stretching and rotation
vk: lightgun crosshair disappears near 0-edge -> scissoring x and y must
be >= 0
always stretch horizontally even when rotating
Fix per-game settings (Issue #115)
Automatic load/save state (Issue #173)
Reload Naomi/AW BIOS after per-game settings are loaded to allow
per-game BIOS region. (Issue #96)
Restrict Soul Reaver widescreen cheat to the EU version (Issue #188)
Disable UI elements for overridden settings
Clean up/simplify legacy Naomi ROM loading
