[ecore] screen size 얻기

#include <stdio.h>
#include <ecore_x.h>

int main()
{
    ecore_x_init(0);
    Ecore_X_Screen* screen = ecore_x_default_screen_get();
    if (!screen) {
        printf("Error\n");
    }

    int w, h;
    ecore_x_screen_size_get(screen, &w, &h);
    printf("%d, %d\n", w, h);
    return 0;
}

ecore_x_init이 되어있지 않으면

ecore_x_default_screen은  crash가 난다.
