Does the gfx tests actually use anything from the resource-bundle?

[tfarina, 2014/05/21 19:03:35]

Yes. Both font_unittests.cc and text_elider_unittests.cc end up calling things
that require ResourceBundle initialization.

[sadrul, 2014/05/21 19:10:21]

Ah, I see. That seems unfortunate. Perhaps we could clean these up.

[tfarina, 2014/05/21 19:28:54]

For further reference the error (without this call) was:

[5967:5967:0521/162544:1047643224706:FATAL:font_list.cc(115)] Check failed:
!(g_default_font_description == NULL). SetDefaultFontDescription has not been
called.

And the list of tests that crashes without this call is:
27 tests crashed:
    FontTest.AvgWidths
    ImageSkiaTest.ArbitraryScaleFactor
    ImageSkiaTest.ArbitraryScaleFactorWithMissingResource
    ImageSkiaTest.BackedBySameObjectAs
    ImageSkiaTest.DynamicSource
    ImageSkiaTest.EmptyOnThreadTest
    ImageSkiaTest.FixedSource
    ImageSkiaTest.GetBitmap
    ImageSkiaTest.GetBitmapFromEmpty
    ImageSkiaTest.ManyRepsPerScaleFactor

    TextEliderTest.ElideRectangleTextLongWords
    TextEliderTest.ElideRectangleTextPunctuation
    TextEliderTest.ElideTextEllipsis
    TextEliderTest.ElideTextEllipsisFront
    TextEliderTest.ElideTextLongStrings
    TextEliderTest.ElideTextSurrogatePairs
    TextEliderTest.ElideTextTruncate
    TextEliderTest.TestFilenameEliding
    TextUtilsTest.GetStringWidth

Hence this call to InitSharedInstanceWithPakPath() be extremely important.
