hwtest shows that, although GS always emit a group of three vertices as one primitive, it still respects to the topology type, as if the three vertices are input into the primitive assembler independently and sequentially. It is also shown that the winding flag in SETEMIT only takes effect for Shader topology type, which is believed to be the actual difference between List and Shader (hence removed the TODO). However, only Shader topology type is observed in official games when GS is in use, so the other mode seems to be just unintended usage.

Among four shader units in pica, a special unit can be configured to run both VS and GS program. GSUnitState represents this unit, which extends UnitState (which represents the other three normal units) with extra state for primitive emitting. It uses lots of raw pointers to represent internal structure in order to keep it standard layout type for JIT to access.
This unit doesn't handle triangle winding (inverting) itself; instead, it calls a WindingSetter handler. This will be explained in the following commits

All the register meanings are derived from ctrulib (3dbrew is outdated for most of them)

Update CryptoPP (byte ambiguity)

Implement fragment lighting in the sw renderer (take 2)

pica: upload shared shader code & swizzle to both unit

Service/dlp: Update function tables according 3dbrew

Quickfix typo in OpenGL 3.3 error message

User pointed out on the Discord server that "nothave" is erroneously concatenated. Added a space to prevent it.

Telemetry: Add several more useful fields

Handle invalid filenames when renaming files/directories

pica/shader_interpreter: fix off-by-one in LOOP

Produce 7zip artifacts on Travis and Appveyor

DynCom VFP tests

Services/APT: Corrected the behavior of the Receive/Send/Glance/CancelParameter functions

Misc shader debugger fixes

Fixed build error "too many initializers for ‘const MacAddress"

Use WinSSPI instead of OpenSSL

Appveyor has OpenSSL installed, so cURL tries to link against it.
This causes dll not found errors because we would also need to ship
OpenSSL, so we link against Windows SSPI instead.
