void GR_UnixPangoGraphics::prepareToRenderChars ( GR_RenderInfo &  ri  )  [virtual]

Do any pre-processing that might be needed for rendering our text (This function is guaranteed to be called just before renderChars(), but where drawing of a single RI item is done inside of a loop, e.g., drawing the different segments of partially selected run, this function can be take out of the loop.)

void GR_UnixPangoGraphics::measureRenderedCharWidths ( GR_RenderInfo &  ri  )  [virtual]

This function is called after shaping and before any operations are done on the glyphs. Although Pango does not have a separate character placement stage, we need to scale the glyph metrics to appropriate zoom level (since we shape % zoom).

NB: this is probably not ideal with int arithmetic as moving from one zoom to another, and back we are bound to end up with incorrect metrics due to rounding errors.

void GR_UnixPangoGraphics::justify ( GR_RenderInfo &  ri  )  [virtual]

We take the same approach as with Uniscribe; we store the justification amount in a separate array of the ri and add it to the offsets before we draw. We will probably need some static buffers to speed things up

It requires as input RI.m_iJustificationAmount and RI.m_iJustificationPoints. These are determined in fp_TextRun using calculations in layout units
