Fixed rendering for piglins, players and other stuff in 26.3 (Iris Vulkan/OpenGL). \*Support for SEUS PTGI HRR 2.1 REFORGED
From 26.x some rendering stuff rendered with Iris shaders turn partly see-through from some camera angles especially against a bright sky/PTGI. Shader effects that work on everything else like world outlines skips completely.
It happens with different shaders like sVision, SEUS PTGI HRR 2.1 REFORGED, Rethinking Voxels, etc. Upstream report: Iris #3105.
Partly transparent pixels in skins are shown either fully visible or fully invisible. Most skins don't have any and most shaders already show them wrong (Iris #3135).
Vanilla draws some rendering stuff with the translucent render type. Iris draws translucent geometry after the shader's deferred passes so effects in those passes never see the entity or other rendering stuff.
IrisRenderFix swaps that render type for cutout the one most mobs use. This rendering stuff are then drawn together with every other solid entity.
