Top Posts Widget: allow non-square image sizes

[stoyan0v]

Fixes #3682

Changes proposed in this Pull Request:

• Add width and height options to $get_image_options, that will allow users to change the size of the image used in Top Posts Widget.

Testing instructions:

• Used to following code to change the image size.

function custom_thumb_size( $get_image_options ) {
        $get_image_options['width'] = 500;
        $get_image_options['height'] = 600;
 
        return $get_image_options;
}
add_filter( 'jetpack_top_posts_widget_image_options', 'custom_thumb_size' );

Is should also work, if you provide only $get_image_options['avatar_size'], but only if you want square images.

Minor docs/comment update, otherwise this is basically the way I was planning on tackling this too.

Should add these to the docblock about jetpack_top_posts_widget_image_options below.

Hey @singerb, I tried to make the code bulletproof, but I totally forgot about the filter docs ( shame on me 😄 ). Thanks for your comment, the new options have been added.

LGTM.

I just left 2 minor comments, but other than that it should be good to go! 👍

Since you're reorganizing this code, could you add a comma, since each line in an array declaration must end with a comma?

[jeherve]

Looks like you have a little typo here.

Thanks @jeherve, I have addressed the issues.
