Reverted stencil mask change. This reintroduces the Scud Race 'ROLLING START' bug. Previous 'fix' did not work for Magical Truck Adventure anyway and also broke some games (Daytona 2 transmission and course select screen, ECA title screen). The stencil mask is not shifted by 16 pixels and I suspect that either there is some unknown trick to horizontal scrolling or that the behavior is affected by hidden raster timing registers hidden in the JTAG interface.

Committing various small updates that have been hanging around in my source tree for a while now:
...
- Added 'crosshairs' command line and config option.
- Added 'vsync' command line and config option (so far only tested on NVidia cards on Windows 7 - other graphics drivers, O/Ss or driver settings may simply chose to ignore this).
- Added fullscreen toggle within game using Alt+Enter key combination.
- Added framework for lamp outputs and 'outputs' command line and config option. So far only the lamps for driving games are hooked up in the emulator (others to be added later).
- Added an initial outputs implementation for Windows that sends MAMEHooker compatible messages (-outputs=win to enable)
- Fixed fps calculation in Main.cpp that was producing incorrect results and so giving the impression that frame throttling wasn't working properly when in fact it was.
- Fixed palette indexed colours as the index was always off by one, causing incorrect colours in various games, eg drivers' suits and flashing Start sign in Daytona 2.
- Altered caching of models so that models with palette indexed colours use the dynamic cache rather than the static one. This is so that changes in palette indexed colours appear on screen, eg the flashing Start sign on the advanced course of Daytona 2 (although currently the START message itself is not visible due to other problems with texture decoding).
- Fixed small bug in TileGen.cpp which meant both palettes were being completely recomputed pretty much with every frame. This was a significant performance hit, particularly as palette recomputation is currently being done in SyncSnapshots (it should be moved out of here at some point, although for now it's no big deal).
- Made sure all OpenGL objects and resources are deleted in Render2D/3D destructors, in particular the deleting of the VBO buffer in DestroyModelCache.
- Made sure that GLSL uniforms are always checked to see if they are bound before using them in order to stop unecessary (but harmless) GL errors.
- Altered the default texture sheet handling to use a single large GL texture holding multiple Model3 texture sheets rather than multiple GL textures as before (if required, the old behaviour can still be selected with the mulisheet fragment shader). I believe this fixes the disappearing crosshairs/corrupt GL state problem which the multisheet fragment shader seemed to be triggering somehow.
- Fixed a bug in debugger which meant memory watches were not triggering properly

Brought in the near clipping plane for Step 1.5+. Objects close to camera are no longer cut-off (e.g., driver arms and steering wheels in cockpit views). Note: This change should probably be applied to Step 1.0 as well in the future. For now, I am leaving the old distance because Step 1.0 coordinates need closer investigation. Bringing in the near clipping plane extends the view frustum depth and will worsen Z-buffer accuracy. Be on the lookout for Z-fighting that did not previously exist.

This update fixes (hopefully) the last of the texture upload lags that were affecting some games, in particular Daytona 2 and Spikeout.
...
To achieve this UploadTextures no longer clears the model cache when called. Instead the cache is kept in-tact (which should help improve cache hits) and all textures referenced by models being rendered are (re-)decoded with every frame.
To help with tracking all the unique texture references contained in a model a new class TextureRefs has been added.

Added support for multiple texture sheets (with up to one per Model 3 texture format) as a rather brute-force way to handle overlapping texture formats in the current 3D engine. This fixes some corrupt textures in Daytona 2 and Virtua Striker 2 (and possibly other games) and also offers a small speed increase when some scenes load multiple overlapping textures.
...
This feature only enables itself when a compatible shader script is loaded. Since none have been checked in yet this means it is currently disabled.

- Texture offsets: models are now decoded for each individual texture offset state and texture coordinates are adjusted while generating the vertex data.
...
- Model LUT now capable of differentiating between texture offset states (linked list of different texture offsets for each model address).
- Removed texOffset uniform attribute from vertex shader -- no longer needed.

Added texture offsets. Vertex shader has been updated in Shaders/Vertex.glsl.
...
Added palette initialization to 2D renderer. Fixes 2D graphics corruption when loading states (most visible in Scud Race).
