This implements the use of VK_FILTER_CUBIC_EXT as a replacement for the software-based bicubic window adapting filter, used primarily for texture sampling in upscaled or downscaled surfaces such as UI, transparency effects, and screen-space elements in Unreal Engine 4 titles.
The Vulkan cubic filter is now conditionally enabled if the following are satisfied:
The device supports VK_EXT_filter_cubic
The format used supports VK_FORMAT_FEATURE_SAMPLED_IMAGE_FILTER_CUBIC_BIT_EXT
This change improves visual quality while reducing GPU workload by offloading cubic filtering to the driver instead of running custom sampling code in shaders. On supported hardware (e.g. desktop GPUs or high-end Adreno/AMD devices), it results in smoother transitions, improved transparency sampling, and better fidelity with lower shader complexity.
Fallback to the original software bicubic logic remains in place for devices lacking the extension or format capability.
Tested on several UE4 titles and confirmed to preserve or enhance visual output, especially in alpha-blended and UI-heavy scenes.

revert [android] Snapdragon 865 patches (#23)
Co-authored-by: Aleksandr Popovich <alekpopo@pm.me>

Reverted due to heavy performance hits on Android with higher specifications, will be adjusted to be included in a specific build for older A6XX devices, as 855, 860, 865, 870, meanwhile it does fix critical issues with certain games crashing due to memory and VRAM usage, hits performance on SoC that can do it without this special flags.
revert [Texture_cache] Better memory handling for devices with lower memory allocations (#233)
Means games like Minecraft Dungeons, Sea of Stars, Luigi Mansion 2, Astroneer, Alan Wake, etc are now playable.
It also cleans up the recent abi.cpp and bindless texture commits a bit.
Everything is in #ifdef ANDROID - The biggest change is CACHING_PAGEBITS = 12.
Without that the way the buffercache grows and joins buffers can cause Android to run out of memory (as you end up with just one big buffer that needs to be copied every time it grows)
Also patches up ffmpeg issues.

Had showed some regressions on devices with higher specifications, will be refined to return as a toggle in a later commit.

- removes provoking vertex, vertex input, dynamic state if not supported
- moves dynamic state to be a 0-3 slider and vertex input its own checkbox
- the rich presence was disabled on linux.
- there were duplicate settings in "edens veil"?
- weird behavior of the vertex input checkbox on per game setting
- adds xenoblade 2 to the d24 conversion control function
- adds the flush logs by line setting to android.
- adds the memory layout setting to android
- Adds the option to show building shaders on the android overlay.

If the user selects dynamic state = 0, force-disable all Vulkan dynamic state extensions and related struct fields.
This ensures compatibility with drivers and simplifies shader pipeline logic.
Also logs all removals for clarity.
If the setting dyna_state is set to 0 (dynamic state disabled), must_emulate_scaled_formats is forced "true" for proper rendering.
If dyna_state is set to 1, 2, or 3 (dynamic state enabled), must_emulate_scaled_formats is forced "false" for proper dyna-state use.
This change applies globally after all device-specific quirks and is logged clearly at boot for easier debugging.
Enhances the Vulkan memory allocator with better OOM handling and memory
alignment:
* Add memory recovery by cleaning up empty allocations before failing
* Implement proper fallback to non-device-local memory
* Simplify memory alignment handling for different vendors
* Add better error logging for allocation failures
* Add IsEmpty() helper to track unused allocations
* Fix alignment requirements for Adreno (4KB) vs other vendors
These changes improve the robustness of memory allocation, particularly
in low-memory situations, and streamline vendor-specific alignment
requirements.
Add workarounds for Samsung Xclipse GPUs:
- Disable extendedDynamicState3ColorBlendEquation as it is broken in Samsung
drivers, similar to AMD drivers
- Add Samsung's proprietary driver to the validated driver list for clock
boosting
- Fix log message to indicate both AMD and Samsung drivers have broken
color blend equation support
Remove stray logical OR operator from validated_driver condition.
- Added missing <thread> header for std::thread usage
- Added <fcntl.h> for O_CLOEXEC and O_NONBLOCK definitions
- Fixed struct initialization order in uffdio_copy to match declaration order

This commit adds Windows-specific implementation of the fault-managed memory
system, providing similar functionality to the existing Linux/Android implementation.
Key changes:
- Added Windows-specific memory management using VirtualAlloc/VirtualFree
- Implemented Windows vectored exception handler for page fault handling
- Added proper memory protection and page fault handling on Windows
- Updated memory snapshot functionality to work on Windows
- Added proper cleanup of Windows-specific resources
- Fixed type conversion issues in memory management code
- Added proper error handling for Windows memory operations
- Fixed VRAM Memory Layout Mode to allow up to 12Gb
The implementation uses Windows-specific APIs:
- VirtualAlloc/VirtualFree for memory management
- AddVectoredExceptionHandler for page fault handling
- VirtualProtect for memory protection management
This change maintains feature parity with the Linux/Android implementation
while using Windows-native APIs for better performance and reliability.

- Memory snapshot and differential snapshot support
- Predictive memory reuse tracking for optimized access patterns
- Vulkan compute buffer integration
- User-configurable settings for enabling features
The system integrates with the existing Vulkan renderer to provide more
efficient memory handling, especially for compute-intensive workloads.
