- enable minifier deadstripping for OpenGL shader format; bytecode is a 100% match with this change on multiple tested projects so it seems safe to enable - deprecate FOpenGLFrontend; nothing in available code appears to inherit from it anymore so the API appears unnecessary. this makes the OpenGL shader format more similar to others (which do not expose compilation functions as API) #rb Jason.Nadro #rb Laura.Hermanns #rb Yuriy.ODonnell [CL 27338803 by dan elksnitis in ue5-main branch]
