8447a22942 VBlank tweaks:
. Removed NTSC_VideoVbl(), since it's not accurate during full-speed. (Nothing was using it)
. Renamed VideoGetVbl() to VideoGetVblBar()
. Correctly pass Vbl (not VblBar) to Mouse's SetVBlank()

02b0d7419a Fixed screen update when running at full-speed
. Specifically IBIZA.DSK demo which streams data from the disk throughout (ie. so runs at full-speed all the time)
. Update the screen every frame, but only if video memory has changed (check AZTEC.DSK loading time)
. NB. When running at full-speed, then 6502 emulation doesn't do cycle-accurate video updates
Fixed crash that could occur when switch video mode (F9) when running at full-speed
. Occured when g_nVideoClockVert was >= 192

66e468db65 Merged in Nick's new native resolution full-screen
- old 640x480 full-screen deprecated

Fixes for:
. Logo & Debug window scaled/positioned correctly
. Buttons & disk activity (on RHS) drawn in correct position
. Crosshairs for mouse (and when using mouse as joystick)drawn in correct position

04c9d09e38 When FullSpeed: don't do cycle-accurate graphics update
. means that disk accesses (eg. loading) is much quicker
Correct naming of video modes (in UI and code)
Pixel adjust for NTSC B&W and Color video modes to align with other video modes

d23ae15774 Removed border from:
. final rendered window
. print-screen bmps (both sizes)
Fixed full-screen so that:
. all mode (RUNNING, DEBUG and LOGO) all occupy the same screen position
. there's no intermediate data drawn out of position when first switching to full-screen
Tested on Win7 and Win10

bc45812f4e Simplified and moved main-loop video update logic into Video.cpp.
Removed complex case below for:
. VideoHasRefreshed(), 'anyupdates'
. VideoCheckPage()

Detailed notes below.

---

Video updates in ContinueExecution() loop:

'anyupdates' gets set if there were any page-flip(s) in last ~17030 cycles:
	anyupdates |= VideoHasRefreshed();
ie. VideoRefreshScreen() was called outside of this loop.

If there's been a call to VideoRefreshScreen() outside of this loop,
  and then the video framebuffer gets written to, ie. VideoApparentlyDirty() returns TRUE,
then don't call VideoRefreshScreen() from this loop for 3 frames.
(If a VideoRefreshScreen() is called outside of this loop then restart the 3 frame count.)

So..
 if the game is flipping, the VideoApparentlyDirty() will return FALSE (since game writes to other framebuffer).
 if the game is not flipping, then VideoHasRefreshed() will return FALSE (since no flips occur).

Therefore this complex case above probably only arises at a boundary eg. when the game is transitioning between these 2 modes,
and so if the emulator does the very occasional screen update in this main loop, it is of no consequence.

(I guess this extra logic was to throttle video updates on very old slow machines)

---

VideoCheckPage(BOOL bForce) was called twice in main-loop:

UnexpectedPage if g_bVideoDisplayPage2 != SW_PAGE2

Once each time through the loop (ie. every 1ms), with bForce=0
	if UnexpectedPage && >500ms since last flip then VideoRefreshScreen()

Once each video frame (ie. ~17030 cycles) when not flipping, with bForce=1
	if UnexpectedPage then VideoRefreshScreen()

Basically this was all about supporting FullSpeed mode, and limiting the calls to VideoRefreshScreen().
