fc27175690 Reduce shader attribute usage by packing floats 
Previously we required 6 shader attributes to pass
in all the required information for the building shader.
By using packing techniques this has been reduced to 4.

This should improve support for integrated graphics cards.

119fb5efe2 Random Buildings - improved texture mapping 
Previously the front and side faces of random/OSM buildings
had identical texture coordinates.  This resulted in the sides
of buildings texture mapping being squeezed or stretched.

This change generates a separate texture mapping for the sides
of the buildings.

564e7b31fd Shader buildings multiple roof types 
Shader buildings now support different roof types
- flat
- gabled
- hipped
- pyramidal

Primarily for osm2city use.

87e9118965 Shader buildings - split wall and roof tex index 
Previously there was very limited texture variations
as a given texture index was used for both the wall
and ceiling.  Now these can be specified separately,
allowing for more variation in both STG defined and
random buildings.
