www/wt: Update to v4.2.2
Release 4.2.2 (March 16, 2020)
This release fixes the following issues:
Security-related: in Wt::Auth the lost password email would be sent to the email address provided in the form, rather than the user's configured email address. While we treat email addresses as case insensitive, it is possible that the mail server may not, and that could potentially be used to steal an account. It is however quite rare for email services to be case sensitive. Issue #7439: ensure that tooltips are always on top, even inside of a dialog. Issue #7448: fixed compilation error on recent versions of MinGW, by using the gmtime_s function on Windows. Issue #7447: fixed text format being reset when the text of a WAnchor is cleared. Fix for WLeafletMap issue that was reported on the forum: signals would get unexposed when options were changed. Issue #7457: moved call to WApplication::require() to the constructor, since calling it in the render function may cause issues. Fixes for WVirtualImage:
Do not render zero width or zero height images. This was possible when
imageWidth or imageHeight was a multiple of the gridImageSize.
Fixed scrollTo() when the image is narrower than the viewport:
scrollTo(0, 0) would not put (0, 0) at the top left when the image was
narrower (or taller) than the viewport.
Issue #7480: prefix Wt's crypt functions to fix issues when linking with libxcrypt, and also set C code's default visibility to hidden. Issue #7468: fixed panning not working properly for a WCartesianChart with plain tooltips. Issue #7482: lastId_ in Postgres backend should be long long. Issue #6774: misc. WTreeView fixes. Fixed use after free caused by order of destruction in WWebWidget destructor.
