John Scipione 1482b250a7 IK: Update scroll bars for alternative control look
Scroll bars should look and work identically to before on
HaikuControlLook.

Add DrawScrollBarButton() and DrawScrollBarThumb() and
DrawScrollBarBorder() methods. These methods are used to draw scroll
bars in a generic way so that they can be drawn differently by alternative
control look's (e.g. BeControlLook). Also it gives us back drawing of
scroll bar knobs.  However the knob setting is not exposed in the
interface in this commit.

These methods are in addition to the 2 existing DrawScrollBarBackground()
methods that draw the scroll bar background. One draws the area above and
below the thumb and the other is called by the first to actually draw the
area.

The rest of the drawing besides the backgrounds was being done in
BScrollBar before. To draw the scroll bar arrows and thumb we were recyling
other ControlLook methods, while this worked well enough on HaikuControlLook
it wasn't flexible enough for alternative control looks.

DrawScrollBarButton() is used to draw the four scroll buttons and is
typically (so far) used in combination with DrawArrowShape().

DrawScrollBarThumb() draws the scroll bar thumb.

DrawScrollBarBorder() draws a 1px border around the entire scroll bar,
potentially B_KEYBOARD_NAVIGATION_COLOR if focused (although this is
feature not currently used.)

Draw unscrollable scroll bars as if they were disabled including the
buttons with their arrow shapes, background, and thumb.

Add FBC backwords compatibility macros in ControlLook.cpp
