Fix initial kerning when there is a horzscale setchromium/2938
Reasoning: the pTextAdvanceX in CPDF_TextObject::CalcPositionData is
being multiplied by horz_scale in CPDF_TextObject::CalcPositionData.
Then, m_pCurStates->m_TextX is updated by this amount. So multiply by
the scale also when updating with initial and final kerning and when
nsegs = 0.
