XCB setMouseCursor

[fundies]

Adds setMouseCursor() function for linux as per issue #269. Please tell me what to put for doxygen comments and anything else to change.

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(800, 600), "My window");
    window.setMouseCursor(142); 

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }
        window.clear(sf::Color::Black);
        window.display();
    }

    return 0;
}

Can you please squash you two commits into one and use a proper commit message?

The discussion on this PR or the feature itself can be found on the forum.

[fundies]

No idea how to do either of those things.

Your implementation uses the built-in cursor font instead of the themed font. You should look into how to use the themed font, or simply use xcb-cursor.

Also, what does 142 mean? You should have an enum or something with the common cursor types.

I updated it to use xcb-cursor. Also I implemented setting cursor to image

xcb-cursor takes strings so new syntax is:

window.setMouseCursor(sf::CursorWait);

For images:

 sf::Image cursor;
    if (cursor.loadFromFile("pencil_1.png"))
        window.setMouseCursor(cursor.getSize().x, cursor.getSize().y, cursor.getPixelsPtr());

Still got some tabs here, but other than that they all seem to be gone.

Windows and Linux now work. I'm having trouble figuring out os x...
