Change the sentinel value for the hslot parameter of run_dma_src to something that is not a valid slot number and actually use it for calls during the active display period

Perform the same slot mapping shift for H32 mode as I did for H40

Shift slot number to slot behavior mapping by six slots in H40 mode. This makes the line change slot align with the point at which the display turns on and off at the end of the active display area. Also fixed a regression in which an external slot got accidentally changed into a sprite draw slot

After reviewing the results of my test ROM again it seems pretty clear that the VBlank flag gets set at the same time as the vcounter changes

Fix calculation of window start column when it's on the right side. This removes graphical glitches in Afterburner 2, Fireshark and Dungeons and Dragons: Warriors of the Eternal Sun and probably others

Pretty decent optimization of vdp_h40 and vdp_h32. Gets reasonably close to the speed of 0.2.0 in the worst case and is faster than 0.2.0 in others

Fix bug in vdp_next_hint that was causing HINTs to fire repeatedly when they should not have fired at all based on an HINT interval that was larger than the number of active lines in the display

Update vscroll latch implementation to be more in line with what Eke-Eke has observed. Revert the change to vdp_cycles_to_line because it breaks hints on line 0. H-Int timing is still a little messed up, but the previous change made things worse.

First pass at emulating a vscroll latch. Titan's Overdrive demo seems to depend on the scroll value being latched early in the line before the HINT gets a chance to change it

Partially working switch to having a vcounter and hslot counter in the context rather than trying to derive them from the cycle count. This should allow for more accurate handling of mid screen mode switches. Interrupt timing is broken currently though
