Holds information needed to draw a shape.
This does not correspond exactly to parsed record in a SWF file, but is used to create both mutable and immutable shapes. A ShapeRecord should have enough methods to implement the AS3 Graphics object (the drawing API of Shape and Sprite). This is restricted to adding fills, paths and line styles (which must be constructed outside this ShapeRecord before being added) and clearing everything. There is no support for removing single elements. ShapeRecord objects are not ref-counted, so they may be stack-allocated or used in smart pointers.

| gnash::SWF::ShapeRecord::ShapeRecord | ( | ) |
Construct a ShapeRecord.
This should only really be used for DynamicShapes. Ideally all immutable ShapeRecords should be constructed with the ctor taking an SWFStream, but some tag formats do not allow this.

| SWF::TagType | tag, | ||
| movie_definition & | m, | ||
| const RunResources & | r | ||
| ) |
Construct a ShapeRecord from a SWFStream.
This is useful for constructing immutable tags.

Parse path data from a SWFStream.
This is used by DefineMorphShapeTag as part of parsing its more complex ShapeRecords.
TODO: is this correct?
When reading font glyphs it happens to read 1 byte past end boundary of a glyph due to fill/line bits being zero.
Generally returning here seems to break morphs: http://savannah.gnu.org/bugs/?21747 And other normal shapes: http://savannah.gnu.org/bugs/?21923 http://savannah.gnu.org/bugs/?22000
So for now we only return if NOT reading a morph shape. Pretty ugly... till next bug report.
