Replaced FFP code that sets up orthogonal projection with explicit matrix calculation. Storing the orthogonal projection in the projection matrix for legacy GL (1.x) rather than in the modelview matrix.

unit uCursor;

interface

procedure init;
procedure updatePosition;

implementation

uses SDLh, uVariables;

procedure init;
begin
    SDL_WarpMouse(cScreenWidth div 2, cScreenHeight div 2);
end;

procedure updatePosition;
var x, y: LongInt;
begin
    SDL_GetMouseState(@x, @y);

    if(x <> cScreenWidth div 2) or (y <> cScreenHeight div 2) then
        begin
        CursorPoint.X:= CursorPoint.X + x - cScreenWidth div 2;
        CursorPoint.Y:= CursorPoint.Y - y + cScreenHeight div 2;

        if cHasFocus then
            SDL_WarpMouse(cScreenWidth div 2, cScreenHeight div 2);
        end
end;

end.
