- video/pc_vga.cpp: Move everything that doesn't belong to main VGA/SVGA interfaces to per-manufacturer family files;
- shared/pcshare.cpp: retire pcat_base_state::pcvideo_* fns;
- video/pc_vga.cpp: temporary move gamtor_vga_device to misc/gamtor.cpp;
- bus/isa/isa_cards.cpp: retire TGUI9680 from being selected (all refs points to be a PCI card only, there's mention of a VLB card but haven't seen a single retail dump/photo yet)
- bus/isa/svga_trident.cpp: add TVGA9000 ISA card
- bus/isa/svga_tseng.cpp: add earlier ColorImage ET4000AX variant
- bus/isa/svga_tseng.cpp: add Kasan Hangulmadang-16 Korean variant ISA
- Adds a very preliminary implementation of nVidia Riva 128 PCI card, added as a temp target in pc/pcipc.cpp (pcinv3);
- video/pc_vga.cpp: Rework and fix VGA input sense (necessary to allow Riva 128 to survive POST);
- video/pc_vga_s3.cpp: Fix s3_vga_device inheritance (was subclassing from ati_vga_device)
- pc/calchase.cpp: convert custom JAMMA i/f to ISA device;
- pc/calchase.cpp: connect Trident VGA to ISA bus;
* machine/mc68328.cpp: Split MC68328 device into a base class with shared functionality, and derived MC68328 and MC68EZ328 models.
* video/sed1375.cpp: Added roughly-functional implementation of the Epson SED1375 LCD controller.
Machines promoted to working
------------------------
3Com Palm IIIc [Ryan Holtz]
- Use 16-bit pointer for sprite RAM storage (despite some systems only having 8-bit CPUs)
- Rename device and move to src/devices
- Clean up variable naming in associated drivers
- neobattl: Add DIP switch locations
- krzybowl: Reduce clocks to match known XTAL value
* Changed to use modern poly.h instead of polylgcy.h.
* Moved helper classes into separate voodoo namespace.
* Derived device classes from video_device_interface.
* Split classes so that later versions derive from earlier versions.
* Created device maps to be directly included.
* Redesigned register mapping to use helper classes and delegates.
* Rewrote rasterizers to use C++ templates instead of macros.
* Added logic to compute equations for color/texture combine units.
* Added special generic identity-texel rasterizer cases.
* Removed pipeline stalls on texture and palette changes.
* Removed pipeline stalls on most all parameter changes.
* Generally re-thought and cleaned up logic throughout.
* Parameterized cycle stealing on status reads; updated all existing voodoo consumers to configure it as it was before.
-vidoe/poly.h: Various improvements:
* Exposed poly_array class for broader use.
* Changed poly_array to intelligently determine maximum size.
* Added logic to track multiple "last" instances in poly_array.
* Extended logic to support up to 16m work items.
* Removed MaxPolys parameter from poly_manager template.
* Added Flags parameter to poly_manager template.
* Added POLY_FLAG_NO_CLIPPING flag to remove clipping code when not needed.
* poly_manager now supports a MaxParams value of 0.
* Made paramcount a template parameter for render_* functions.
* Added reset_after_wait() method to be overridden by derived classes.
* Switched to using std:: helpers instead of internal methods.
* Removed useless dependency on screen_device.
* TRACK_POLY_WAITS now produces more complete statistics.
-video/polylgcy.cpp: Removed legacy implementation of polygon renderer.
-machine/gt64xxx.cpp: Prevent lockups by disallowing 0-duration timers.
-machine/pci.cpp: Added support for adding subdevice maps directly.
-emu/video/rgbsse.h: Improved min/max for SSE4.1+ and scale+clamp operations for all.
-emu/vidoe/rgbutil.h: Made palette expansion constexpr and added argbexpand function.
-osd/osdcore.cpp: Changed osd_ticks to use QueryPerformanceCounter on Windows since the mingw std::chrono::high_resolution_clock is anything but.
