* src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of

ttmetrics here.  TrueType fonts with only sbits always have
ttmetrics.valid set to false.

* src/truetype/ttgload.c (TT_Load_Glyph): Check that ttmetrics is
valid before loading outline glyph.

* src/cache/ftcimage.c (FTC_INode_New): Fix a memory leak.
