Adds hardware-accelerated shader built-in functions for specific texture gather patterns (linear 4x1, 2x2 vertical, 2x2 horizontal, and diagonal) via a new OpImageGatherQCOM SPIR-V instruction. These patterns are optimized for use cases such as super resolution upscaling and contrast-adaptive sharpening on Adreno GPUs. Also introduces a new VK_FORMAT_FEATURE_2_BLOCK_MATCHING_SXD_BIT_QCOM format feature flag to properly expose format support for OpImageBlockMatchSSDQCOM and OpImageBlockMatchSADQCOM independently of the windowed/gather block match operations.
The task list for the VK_QCOM_image_processing3 release is:
As each component is made public, the task will be checked off. When all tasks have been completed this issue will be closed and the extension will be fully released.
