Note
Note that the PageLayoutView has changed a lot in newer TYPO3 versions,
make sure to update your code accordingly.
The way registering the hook has changed in ext_localconf.php:
// Prior TYPO3 8
// $TYPO3_CONF_VARS['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem'][] = 'EXT:extensionkey/Classes/Hooks/PageLayoutViewDrawItemHook.php:&Vendor\\Extensionkey\\Hooks\\PageLayoutViewDrawItemHook';
::
// TYPO3 8:
$TYPO3_CONF_VARS['SC_OPTIONS']['cms/layout/class.tx_cms_layout.php']['tt_content_drawItem'][] = 'Vendor\\Extensionkey\\Hooks\\PageLayoutViewDrawItemHook';
