Description
Can be reproduced on Windows with manually reducing the glyph cache texture size to 256 and running the modified qmldatainput example that plays back song lyrics with Chinese characters for exhausting the cache.

Tried backporting changes* done to QtDeclarative for the glyph cache fixing similar issues but the issue still remains. it crashes in Windows in GPU libraries because (uninitialized) texture size being allocated is over the max texture size.
