/**
 * Detect if popup opening is blocked by user browser native blockers.
 * Native blockers are for example in IE 7: Tools -> Popup Blocker, FF 3:  Tools -> Options -> Content tab -> Block pop-up windows.
 * "Popup opening" is meaning using window.open() call from script without user direct interaction
 * (user interaction would be e.g. clicking on link and using window.open call from click listener).
 *
 * Check is done using preemptive window.open() call. When popups are blocked, then window is not opened
 * and code can make further actions based on that fact. Downside is that when popups are not blocked, user sees
 * for a little period of time empty popup-testing window, which is closed right away. To remedy, popup-testing
 * window will be made with exact dimensions of client window under it. Please note that blurring window is not an option
 * (to hide it behind main window), it will activate only after window is fully opened and even slows process down a bit.
 *
 * [!] In IE it is impossible to make popup-test window without statusbar and locationbar. 
 * This causes popup-test window being with different dimensions than original window.
 * 
 * [!] In Chrome it is not possible to make opening test using conventional means of checking if test window is opened.
 * When popup blocker is on, Chrome opens the popup, loads the page, and parses all the Javascript on the "blocked popup". 
 * It just doesn't display the popup to the user. In Chrome src code it is called ConstrainedWindow.
 * 
 * For Chrome timeout + innerHeight reading scheme is used:
 * 		[1] make regular popup test with test-window
 * 		[2] set timeout to read test-window innerHeight value after some time (to ensure that page is fully loaded)
 * 		[3] if innerHeight value is still 0, it is strong indicator that popup was blocked
 * 		[!] note that until test-window is loaded, innerHeight value is always 0, no matter if blocked or not 
 * 
 * [!] When window.open() call is specifying position of window (top, left), all negative values are
 * retranslated either into some default values or 0 depending on browser;
 *
 * If popups are not blocked, write result into browser cookie and do not check any more (read always cookie contents before check).
 * If popups are blocked, set client parameter and show client alert right after client loading.
 * 
 * Test for IE6+, FF3+, Safari, Chrome
 * [!] Chrome has cookie writing disabled while testing from local filesystem
 * [!] IE doesn't block popups from localhost, even when blocker turned on, but blocks from local filesystem
 * 		[1] clear cache and cookies, set browser blocker on and start client;
 * 			verify that blocker alert appears in client
 * 		[2] set browser blocker off and start client;
 			verify that blocker alert doesn't appear and cookie "playtech.casino.blocker.detection.done" is written
 * 		[3] just after completing [2] set browser blocker on and start client;
 * 			verify that cookie is checked and thus no alert is appearing in client.
