Anurag Thakur b1f9f98e45 [dense] Add support for rendering prelines 
* src/dense/ftdense.c: Add dense_render_line2 function, that takes
a PreLine as argument.

FT_Outline_Decompose call in dense_render_glyph replaced by a loop
that renders PreLines

* src/dense/ftdenserend.c: Add support for shifting PreLines as
per target bitmap
