Notes:
Oxygen Builder
	Modals, on close, reset src attribute of iframes to stop running videos. 
	That is done by this.src = this.src, which also kills event handlers we assigned.
	If a modal is closed with a playing video, it's stopped, but we'll lose control 
	over it since we don't get any further events. 

TESTED WITH:
Product		Versions
--------------------------------------------------------------------------------------------------------------
PHP 		7.4, 8.1, 8.2
WordPress	6.4.2, 6.4.3, 6.5, 6.5.2, 6.5.3, 6.5.5
Bricks		1.9.5, 1.9.6, 1.9.7, 1.9.8, 1.9.9
Oxygen		4.8.1, 4.8.2, 4.8.3
--------------------------------------------------------------------------------------------------------------

Version History:
Date		Version		Description
--------------------------------------------------------------------------------------------------------------
2024-07-04	1.4.0		New Features:
						- Support for unlisted Vimeo videos with hash parameter "h" in shortcode or URL
						- Loading more thumbnail sizes from Vimeo 
						Changes:
						- Replaced deprecated Vimeo SimpleAPI by oEmebd
						- Cache JSON format has changed due to the change from SimpleAPI to oEmbed
-			1.3.1		Changes
						- Added width and height attributes for thumbnail inages
2024-04-28	1.3.0		Reorganization of code base.
						New Features:
						- For better accessibility, the Enter key can now be used to start and stop videos.
						  (Thanks to Stephan Koenigk for his feature request and üre-release tests)
						Changes:
						- For invalid IDs, don't create directory, store json, attempt to retrieve thumbnails
						- In Builders Bricks and Oxygen, click handler is deactivated to allow selecting element
						- Preparation for Bricks Element. Coming soon.
2023-12-30	1.2.0		New Features:
						- Complete rebuild of JS
						- Now using Vimeo Player API to provide more control
						- Video player management via players registry and observer
							- Pause current video if another one is started
							- Pause video if modal/popup closed (evaluated by visibility of parent DOM element)
						- Support for dynamically embedded videos using AJAX calls:
							- Removed init prevention for AJAX calls
							- Added PHP method MA_GDPR_Vimeo::enable_footercode() to trigger output of footer
							  code (styles, scripts, svg) for video embeds dynamically loaded by AJAX calls
 							- Play click handler is now assigned as onclick event instead of collecting all 
							  videos after page load. This eliminates the need for an extra click handler 
							  initialization for players dynamically loaded after page load.  
						- Optimizations for accessibility 
						Fixes:
						- Prefixed wrapper/player IDs with snippet slug to prevent IDs starting with number
						- Fallback for aspect ratio via padding-top (CSS variable, @supports rule) 
						  for older browsers not supporting aspect-ratio like Safari < V15
2023-11-09	1.1.1		Fix: "Attempt to assign property 'notes' on null" error in get_video_details()
2023-04-04	1.1.0		New Feature: Pause handler for closed Oxygen Modals
2023-04-03	1.0.0		Initial Release
2023-04-02	0.0.0		Development start
