View2D: Cosmetic changes and bugfixes

* Scrollers now draw using nice rounded+shaded style everywhere

* When scrollers 'bubble' completely fills a scroller or is completely out of view, the view zooming using the handles is now only activated if the mouse is within a quarter of the total length of the scroller on either end of the scroller. Otherwise, pan is activated. This should make the scrollers more usable in anim editors.

* Fixed drawing of gridlines in TimeLine - needed to adjust ymin value of cur and tot rects to accomodate for the new mask/cur adjustments as old TimeLines didn't draw with 'real' scrollbars. Also, adjusted min/max values to fit these new tot/cur rect y-sizes.

* Tidying up vars and fixing errors in declaring new View2D types in preparation for simpler method of initialising views...
