BeControlLook: Fix app integration drawing issues

Update BTab::DrawTab() to pass the current index, the index of the
selected tab, and the index of the first and last tabs into
BControlLook::DrawActiveTab() and BControlLook::DrawInactiveTab().
This allows you to draw tabs differently in your BTab or BControlLook
subclass in many different circumstances.

Modify BControlLook API to add indexes to DrawActiveTab() and
DrawInactiveTab() like so:

void DrawActiveTab(..., int32 index = 0, int32 selected = -1,
int32 first = 0, int32 last = 0);
void DrawInactiveTab(..., int32 index = 0, int32 selected = -1,
int32 first = 0, int32 last = 0);

These extra indexes are not used by HaikuControlLook which relies only
on if the tab is active or inactive to draw.

Add IndexOf(BTab* tab) method to BTabView and document it to get the
index of the current tab in BTab::DrawTab(). Also add a warning in the
BTabView::DrawTab() method not to use the position and full parameters
anymore, use BTabView::IndexOf(), BTabView::Selection(), and
BTabView::TabCount() to get the info you need.

Using a dynamic_cast to a BTabView in BeControlLook to determine if the
view is derived from a BTabView didn't work in the case of WebPositive.
Furthermore, WebPositive does custom tab drawing which needed to be
updated for alternative control look. These index parameters passed from
BTab to BeControlLook allow us to draw the tab like BeOS without relying
on a dynamic_cast to BTabView to get the info.

Reproduce the functionality described above for BTab in WebPositive's
custom tabs. Eliminate no longer needed code in favor of using indexes.
Update WebPositive custom tabs to use BControlLook::DrawTabFrame()
instead of BControlLook::DrawInactiveTab() matching the update made in
BTabView.

In BeControlLook::DrawTabFrame() fill rect with base color, WebPositive
doesn't draw any tab background, so it expects this work to be done for
it.

Eliminate hasFrames variable from WebPositive.

Rename TabSelected(index) to UpdateSelection(index) in WebPositive to
better reflect its purpose.

Adjusted HaikuControlLook::DrawInactiveTab() to draw the tab borders more
selectively. Only draw border if left border is set for top and bottom tabs
or top border is set for left and right tabs. Undo no longer needed frame
manipulation border drawing workaround in HaikuControlLook::DrawTabFrame().

Draw scroll bar triangle without using DrawArrowShape().

Unlike in HaikuControlLook, DrawArrowShape() is used to draw arrows in
BOutlineListView and menus distinctly from how it draws arrows in scroll
bars. Draw our distinct arrows in DrawSrollBarButtons() instead.

This fixes overflow of time edit up-down arrows in Clock prefs and the
collapse-expand arrow in Deskbar not being vertically centered.

In DrawBorders() only inset if we actually draw the border.

Fix alignment issues with DrawSliderThumb dots for example in
MediaPlayer volume knobs.

Draw using line arrays calling AddLine instead of StrokeLine in
several places.

DrawMenuBar() extends to draw final pixel which eliminates an extra
lines at the end of menu bars.

Truncate button labels better fixing a few issues for example keymap
keyboard layout button labels. Button insets has been updated a bit
to fix drawing issues with buttons missing a border.

Using a dynamic_cast to a BButton to determine if a view is a button
in BeControlLook didn't work in the case of the keymap label. Look for
B_FLAT, B_HOVER, or B_DEFAULT_BUTTON flag in BeControlLook::DrawLabel()
to draw the label inverted on click. Pass the B_FLAT flag from Keymap
keys when drawing using BControlLook so that the label is inverted.

WebPositive: Removed wrong license text from all files ...

... which were technically never distributed by Apple nor
are derived from code distributed by Apple. Only BrowserApp
and BrowserWindow were originally derived from code that used
to be part of WebKit and was distributed by Apple.

Style changes only

Make the max tab width always 300px instead of being proportional to the label
text. I think a consistent tab size is more important. Also made the minimum a
little smaller (60px.)

git-svn-id: http://svn.haiku-os.org/webpositive/webkit/trunk@559 94f232f2-1747-11df-bad5-a5bfde151594

* Reworded defines in Jamfiles to make them more readable.
* Split WebTabView into several files in a new sub-folder "tabview".
* Implemented scrolling the tab view left/right when there are more tabs than
fit into the view.
* Fixed graphic glitches in the TabContainerView when the window is resized,
the space behind the last tab was not managed properly.
