Eskil Abrahamsen Blomfeldt c9d991de1f Fix missing text when Harfbuzz fails to shape a substring
This amends fccd419dd6.

If Harfbuzz failed on one of the items in a string and returned
zero glyphs, then we would exit the shaping loop. The mentioned
change fixed a crash related to this when the ignored character
was the only character in the string, but it occurred in a
subitem of a longer string, then we would return and fail to
lay out the rest of the string.

This popped up recently because an update to Harfbuzz has caused
it to return zero glyphs when applying the Apple emoji font to
an isolated variant character (see bug report). When we matched
the symbol to the main font and only the variant character to
the emoji font, we would get in this situation, and end up
exiting the shaping early.

[ChangeLog][QtGui][Text] Fixed a regression which would
sometimes cause text to disappear if the string contained
an unmatched variation selector character.

Pick-to: 6.4

This directory contains autotests and benchmarks based on Qt Test. In order
to run the autotests reliably, you need to configure a desktop to match the
test environment that these tests are written for.

Linux X11:

   * The user must be logged in to an active desktop; you can't run the
     autotests without a valid DISPLAY that allows X11 connections.

   * The tests are run against a KDE3 or KDE4 desktop.

   * Window manager uses "click to focus", and not "focus follows mouse". Many
     tests move the mouse cursor around and expect this to not affect focus
     and activation.

   * Disable "click to activate", i.e., when a window is opened, the window
     manager should automatically activate it (give it input focus) and not
     wait for the user to click the window.
