I didn't found #webkit in the list when I used the IRC chat client software.

#webkit-efl is not likely as useful as #webkit. EFL is just a port, #webkit is
where the core devs hang out.

Any way...
I'm working on a new text layout scheme for webkit
That sounds like a bad idea... What do you mean by a new text layout scheme?
Is it spec'd anywhere? Does any other browser do the scheme in question? How
does it interact with CSS layout?
and I needed to find out:
1. Does webkit renders bitmap glyphs before it starts to do layout or it just
uses the data from font file for metrics?
WebKit does not render glyphs. The platform's font system does.
Source/WebCore/platform/graphics (and /text) have abstractions for taling to
the various platform font systems.
2. If it does, where does it save the bitmap glyphs and if not where it saves
the data from font file?
Again, this is all handled by the underlying platform libraries. WebCore keeps
a glyph cache. Where it caches glyph identifiers (pointers on some platforms)
as well as some measurement information per-character. But it just hands those
identifiers off to the platform again to do the drawing.
3. I need to find out where it gives the layout engine the size of the block
for text and the position of the block on screen?
This sort of information is calculated during layout() and stored on the
RenderObjects. RenderBoxModelObject is the superclass for all RenderObjects
which layout according to the CSS box model (which you can search for on google
and read more about). Search for my name on YouTube to find a video describing
some of this.
Thanks for your attention
Again, inventing a new layout scheme is probably a bad idea. Designing one in
a research paper is fine, but you probably won't want to implement it... :)
SVG Text has some of its own line layout. You'll need to learn more about the
line box tree. (InlineBox and subclasses.) MathML also does some of its own
layout modifications on top of CSS line layout.
Best of luck.

Did you find your answer? I'm on #webkit as 'eseidel'

Best to discuss this on #webkit.

In the while loop on line 1944 of RenderBlockLineLayout.cpp the script
should use the width of characters from glyph metrics to determine where to
put the line break. I want to know where it looks for that data. I did
searched and grep the webcore/platform/graphics before but nothing useful
in glyph header files so far!

Look under Sources/WebCore/platform/graphics.
Or just grep the source directory for glyph. :)
