- renamed trigger_timer() methods to refresh_display()
- new argument 'redraw' added to force a refresh of the entire screen
  (used in snapshot mode)
- siminterface method refresh_vga() now checks if the Bochs gui init is complete
- use SIM->refresh_vga() in some more cases

4eae421272 Graphics snapshot feature re-implemented for the new graphics API
- graphics_tile_info() split into a common and specific part
- store snapshot mode in structure bx_svga_tileinfo_t
- in snapshot mode, display adapters copy raw data to buffer
- rewrite of the trigger_timer() code to make it work in all cases
- added new class bx_nonvga_device_c to make forwarding refresh requests to the
  Voodoo adapter possible

  (division by zero error)
- handle PCI register 0x40 (initEnable)
- fixed reported display size

5f5d8e2c33 Applied initial version of the 3dfx Voodoo Graphics emulation. The Voodoo core
is based on a patch originally designed for DOSBox. Currently only the Voodoo1
adapter model can be emulation. The emulation is currently slow, but we intend
to clean up and optimize the code. Running the 3D engine in a separate thread
is also planned. To compile with Voodoo support the configure option
"--enable-voodoo" must be used. Then the device can be activated with
"plugin_ctrl: voodoo=1" in bochsrc or on the command line. The device will be
assigned automatically to a PCI slot unless you do that manually. A specific bochsrc
option to select the adapter model will be added when the code has support for it.
