Detailed Description
encapsulates output of GR_Graphics::shape() which is passed as input to GR_Graphics::renderChars().
This is abstract class and suitable functionality is to be provided by platform code.
Notes on append(), split() and cut()
These functions allow our fp_TextRun to merge with next or to split into two without having to know about various platform dependent chaches that speed up shaping and drawing; append() joins all such chaches, while split() splits them into two. Before spliting, split() must allocate appropriate GR_FERenderInfo into pri.
cut() attempts to remove a section of length iLen starting at offset without re-shaping the whole buffer; if it succeeds it returns true; if it fails and the chaches need to be re-calculated it return false (it should not carry out the reshaping per se)
m_iOffset and m_iLength contain offset and length pertinent to the current operation and their state is undefined: the user should always set them if the function to which GR_RenderInfo is passed is going to use them
