Subject: - Moved most types and StructLayout to runtime package:
com.jogamp.gluegen.cgram.types -> com.jogamp.gluegen.runtime.types This is
required for desired runtime memory layout.
- Split CompoundType to StructType + UnionType
- StructLayout:
- Utilizing SizeThunk alignment
- Alignment
1) Natural type alignment
2) Add Size
3) Trailing padding w/ largest element alignment
- Only perform memory layout once for type.
Status:
- Unit test passes w/ static MachineDescriptor64Bit
- FIXME static 32bit is faulty, uses 64bit size/alignment
- TODO runtime struct layout to please all platforms w/o worrying
