???
Looking in the implementation of CairoOutputDev::beginType3Char the code of the
glyph is not saved or used, it always return gFalse, therefore Gfx calls
display for the charProc and the endType3Char always, and
CairoOutputDev::endType3Char just restores what is saved in beginType3Char. Is
there some magic I don't understand?
On the other hand, I missed that splash indeed uses sometimes the cached glyphs
for this PDF, I missed that somehow in my first investigation. And the
rendering time increases a little bit
w using the cache
real 0m0.182s
user 0m0.163s
sys 0m0.021s
w/o using the cache
real 0m0.214s
user 0m0.200s
sys 0m0.018s
So I fear I need some more time for investigation.</pre>
