Capture/Replay: Capture glUniformBlockBinding()

eFootball PES 2021 uses glBindBufferRange(), which requires glUniformBlockBinding() to create the pairing of uniform block indexes to buffer bindings. The uniform buffer indexes that are assigned when each program is linked can differ between drivers, so the glUniformBlockBinding() calls need to be recorded to get the correct index values for the glBindBufferRange() calls.
