Articulation tweaks

[mike-spa]

Three separate jobs:

• A small modification of default styles.
• Correcting the alignment of composite staccato/tenuto marks.
• Improving the efficiency when fetching the category of a given articulation mark (it doesn't makes sense to perform all those comparisons every time we need to query it, makes more sense to compute them once and store them).

To reduce memory usage, you could store these using a single field of flags. But I'd first ask @vpereverzev if he thinks that's better.

Anyway, to do that, you would create an enum like this:

enum class ArticulationCategory: char { // char makes sure that this will use only 1 byte, 
                                        // which consists of 8 bits, 
                                        // which is enough to store these 6 flags
    None = 0x00
    Double = 0x01
    Tenuto = 0x02
    Staccato = 0x04
    Accent = 0x08
    Marcato = 0x10
    LuteFingering = 0x20
}

Then create a Flags from that enum: (you need to #include "flags.h" for this)

DECLARE_FLAGS(ArticulationCategories, ArticulationCategory)
DECLARE_OPERATORS_FOR_FLAGS(ArticulationCategories)

Then replace all these members with:

Suggested change

	bool _isDouble = false;
	bool _isTenuto = false;
	bool _isStaccato = false;
	bool _isAccent = false;
	bool _isMarcato = false;
	bool _isLuteFingering = false;
	ArticulationCategories m_categories = ArticulationCategory::None;

Then replace the is... methods with:

    bool isDouble() const { return m_categories & ArticulationCategory::Double; }

etc.

Then modify computeCategories like this:

m_categories.setFlag(ArticulationCategory::Double, 
                     _symId == SymId::articMarcatoStaccatoAbove || _symId == SymId::articMarcatoStaccatoBelow
                     || _symId == SymId::articTenutoStaccatoAbove || …)

Thanks! I'll try!
