app_server: avoids referencing a temporary IntRect instance.

* GCC lets us use a const reference to a temporary, but using it after it disappeared
is incorrect.
* reverts hrev45576 as this patch seems more correct.

app_server: workaround for GCC 4.7 misbehavior in IntRect.

* moved the inlined BRect constructor of IntRect to the cpp file. GCC will inline the method
anyway.
* impacted methods were both AGGTextRenderer::RenderString() in
src/servers/app/drawing/Painter/AGGTextRenderer.cpp, calling the StringRenderer constructor
with a BRect reference.
* unless someone comes up with an explanation, I'll try to come with a smaller testcase to
submit this problem upstream.

* introduced IntPoint and IntRect, which are just like BPoint and BRect,
but use integer coordinates. These are now used in ViewLayer for the
coordinate system (layout, scrolling offset, view bitmap layout)
* modest performance improvements by inlining some very often used
methods, and by preventing to go down the entire layer tree too often,
for example InvalidateScreenClipping was always called in the deep
mode, therefor it is save to assume that the tree does not have to
be traversed as soon as the clipping is already invalid
