v6.338.2 This release fixes a number of minor issues with v6.338.1, in particular a fix for the new caching subsystem when using custom cache callbacks. Fixes and performance improvements: - properly align AVFrame planes when using oddly-sized pixels - correct some reported GPU buffer size limits - properly report texture transfer failures - avoid ICC-related error spam - avoid using some deprecated APIs and syntax - fix pl_find_filter_* missing symbols - fix duplicate initialization of vulkan debug layers - fix assertion when using custom cache allocator API - avoid redundant scale shader variable declarations - avoid redundant linearization step when using sigmoid scaling - avoid generating redundant dependency on xxhash - fix possible integer overflow on 32-bit textures - fix cropped frame dimensions when using vulkan hwframes
