PHP Editor Review - Gtk Manual Gtk gtkwidget method shape Combine Mask

GtkWidget::shape_combine_mask

void shape_combine_mask( GdkBitmap shape_mask , int offset_x, int offset_y);
This method can be used to give widgets an unnormal shape, e.g. a circle or something angulary. You can use it with all types of widgets, e.g. buttons and even windows. But see yourself:
Example 59. Making an unusual shaped button
<?php
if( !extension_loaded('gtk')) {
    dl( 'php_gtk.' . PHP_SHLIB_SUFFIX); 
}
