Camera movement settings should be configurable

[oscujic]

The movement settings for the camera are hard coded, meaning if someone wants different settings, they essentially have to write their own implementation.

rcamera.h, starting line 200:

#define CAMERA_MOVE_SPEED                           5.4f       // Units per second
#define CAMERA_ROTATION_SPEED                       0.03f
#define CAMERA_PAN_SPEED                            2.0f

// Camera mouse movement sensitivity
#define CAMERA_MOUSE_MOVE_SENSITIVITY               0.003f

// Camera orbital speed in CAMERA_ORBITAL mode
#define CAMERA_ORBITAL_SPEED                        0.5f       // Radians per second

My suggestion is that these should be made configurable variables (like FOV already is).

I agree with this suggestion. Having these values hard-coded in rcamera.h makes it difficult to customize the camera controller without modifying raylib's source.

I think the important part is to keep the current behavior as the default, while allowing applications to override the values when needed.

One possible approach would be to introduce a CameraSettings (or similar) structure containing the movement parameters:

typedef struct CameraSettings {
    float moveSpeed;
    float rotationSpeed;
    float panSpeed;
    float mouseSensitivity;
    float orbitalSpeed;
} CameraSettings;

The existing values could remain as the defaults, so existing code would behave exactly as it does today.

I would also keep these settings separate from Camera3D. Camera3D describes the state of the camera, while these values describe how the camera is controlled. This separation would make it possible to have different controllers/settings for the same camera, or different settings for different cameras.

Another advantage is that this could eventually allow users to implement their own camera controllers while still reusing the existing rcamera functionality.

Overall, I think making these parameters configurable would be a useful improvement, especially for games that need different camera speeds or mouse sensitivity depending on the camera mode.
