v5.264.1 This bugfix release fixes a major regression in the v5.264.0 tone-mapping redesign which resulted in garbage pixels (and unnecessary tone-mapping) when using an ICC output profile, as well as other minor miscellaneous fixes. Fixes: - fix linear tone mapping resulting in garbage pixels appearing in and around black and near-black regions - fix ICC profiles incorrectly resulting in tone-mapping being enabled - fix minimum meson version being incorrectly set - fix HDR10 static metadata minimum brightness not being sent when using HDR passthrough - fix left-over debug junk that could possibly cause a shader miscompilation on older GLSL - fix a possible memleak in pl_renderer - fix several hypothetical sources of UB inside internal code - various minor fixes to misleading or missing log messages
