        commit cfb5a20779e4229a375c83e4821a108e1f3c836f (v1.4.8 era),

Used only by tests/test_gl_multiview_fbo.py: native/glmv/glmv_rewrite.h must turn every vertex shader's
`layout(num_views=NUM_VIEWS) in;` and every gl_ViewID_OVR into a single-view shader (frame.gl_multiview_fbo,
GitHub #77). These are the same 19 shader strings the v1.4.8 APK's libdoom3.so contains.
