…t if 5 is a special constant or based on resolution)

This request can cause issues if the user denies the microphone permission.
Calling requestPermissions causes GrantPermissionsActivity to be launched.
Citra's MainActivity will pause. GrantPermissionsActivity will immediately
finish as the user has already denied the permission. Citra's MainActivity then
gets resumed and then tries to request the permission again forming a loop.

 Move request for microphone permission to onCreate

 into lubos_immersive_mode

Uses a smaller radius screen which fits just within the view bounds and therefore has a higher resolution, but still feels "immersive". I also lowered the lower screen so it doesn't obscure the smaller main panel.

This means the same shaders can be used for both immersive and non-immersive as the uniform itself it the toggle in the GLSL rather than generating two different instances of the shader.
Furthermore, only one place where the gl_Position was being modified was actually needed; the other two seem to be able to be removed without it preventing immersive mode from working.

Pass the vr_use_immersive_mode as a Vertex Shader Uniform flag
