drawinglayer: clang-format BasePrimitive2D + remove from blacklist
No functional change was made, only formatting of the code. The code was formatted with clang-format and moves the files baseprimitve2d.{cxx,hxx} out of blacklist so it will be auto formatted with every change from now on.

- /** BasePrimitive2D class
-
- Baseclass for all C++ implementations of css::graphic::XPrimitive2D
-
- This class is strongly virtual due to the lack of getPrimitiveID() implementation.
- This is by purpose, this base class shall not be incarnated and be used directly as
- a XPrimitive2D.
-
- It is noncopyable to make clear that a primitive is a read-only
- instance and copying or changing values is not intended. The idea is to hold all data
- needed for visualisation of this primitive in unchangeable form.
-
- It is derived from cppu::BaseMutex to have a Mutex at hand; in a base
- implementation this may not be needed, but e.g. when buffering at last decomposition
- in a local member, multiple threads may try to decompose at the same time, so locking
- is needed to avoid race conditions seen from the UNO object implementation.
-
- A method to get a simplified representation is provided by get2DDecomposition. The
- default implementation returns an empty sequence. The idea is that processors
- using this primitive and do not know it, may get the decomposition and process
- these instead. An example is e.g. a fat line, who's decomposition may contain
- the geometric representation of that line using filled polygon primitives. When
- the renderer knows how to handle fat lines, he may process this primitive directly;
- if not he can use the decomposition. With this functionality, renderers may operate by
- knowing only a small set of primitives.
-
- When a primitive does not implement get2DDecomposition, it is called a 'Basic Primitive' and
- belongs to the set of primitives which a processor should be able to handle. Practice
- will define this minimal sets of primitives. When defined and the concept is proved,
- unique UNO APIs may be defined/implemented for these set to allow more intense work
- with primitives using UNO.
-
- Current Basic 2D Primitives are:
-
- - BitmapPrimitive2D (bitmap data, evtl. with transparence)
- - PointArrayPrimitive2D (single points)
- - PolygonHairlinePrimitive2D (hairline curves/polygons)
- - PolyPolygonColorPrimitive2D (colored polygons)
-
- UPDATE: MetafilePrimitive2D (VCL Metafile) is taken off this list since
- it is implemented with the integration of CWS aw078 into DV300m69.
-
- All other implemented primitives have a defined decomposition and can thus be
- decomposed down to this small set.
-
- A renderer implementing support for this minimal set of primitives can completely
- render primitive-based visualisations. Of course, he also has to take states into account
- which are represented by GroupPrimitive2D derivations, see groupprimitive2d.hxx
-
- To support getting the geometric BoundRect, getB2DRange is used. The default
- implementation will use the get2DDecomposition result and merge a range from the
- entries. Thus, an implementation is only necessary for the Basic Primitives, but
- of course speedups are possible (and are used) by implementing the method at higher-level
- primitives.
-
- For primitive identification, getPrimitiveID is used currently in this implementations
- to allow a fast switch/case processing. This needs a unique identifier mechanism which
- currently uses defines (see drawinglayer_primitivetypes2d.hxx). For UNO primitive API
- it will be needed to add a unique descriptor (Name?) later to the API.
-
- This base implementation provides mappings from the methods from XPrimitive2D
- (getDecomposition/getRange) to the appropriate methods in the C++ implementations
- (get2DDecomposition/getB2DRange). The PropertyValue ViewParameters is converted to
- the appropriate C++ implementation class ViewInformation2D.
-
- This base class does not implement any buffering; e.g. buffering the decomposition
- and/or the range. These may be buffered anytime since the definition is that the primitive
- is read-only and thus unchangeable. This implies that the decomposition and/or getting
- the range will lead to the same result as last time, under the precondition that
- the parameter ViewInformation2D is the same as the last one. This is usually the case
- for view-independent primitives which are defined by not using ViewInformation2D
- in their get2DDecomposition/getB2DRange implementations.
