Subject: [PATCH] render: fix refcounting of glyphs during ProcRenderAddGlyphs
Previously, AllocateGlyph would return a new glyph with refcount=0 and a
re-used glyph would end up not changing the refcount at all. The
resulting glyph_new array would thus have multiple entries pointing to
the same non-refcounted glyphs.
AddGlyph may free a glyph, resulting in a UAF when the same glyph
pointer is then later used.
Fix this by returning a refcount of 1 for a new glyph and always
incrementing the refcount for a re-used glyph, followed by dropping that
refcount back down again when we're done with it.
