Subject: Port QUrl/QSizeF away from QQmlVmeVariant
X-Git-Tag: v5.5.90+alpha1~59
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0cbab3b17fb70208476b910d7d82ae653a9a1050;p=platform%2Fupstream%2Fqtdeclarative.git

Port QUrl/QSizeF away from QQmlVmeVariant

Store QUrl/QSizeF in a javascript array. The values are wrapped inside
a QV4::Variant. This is part of a series sliming down the memory
usage of properties.
