## Description of change
Subscreen overlay window used to draw above the main game surface, but
below any other ImGui widgets. Fix this so that the subscreen image is
drawn at the same z-level as the sub window itself.
This has been a long-standing issue - at least since 2023 when spice2x
first forked...
## Testing
Tested TDJ in windowed mode.

When DLL is configured to use TDJ I/O but spice is in LDJ mode, show an
error in LED ticker suggesting the user to turn on `-iidxtdj`.
When DLL is configured to use LDJ I/O but spice is in TDJ mode, show an
error in TDJ overaly suggesting the user to fix the DLL.
Fix a small bug that caused a white window to be created when `-w` is
enabled even when `-iidxtdj` is not, but DLL is using TDJ I/O.

## Description of change
In cases where the subscreen overlay window does not have anything to
show (either via misconfiguration or an error), ensure that the window
border is shown with the close button. Additionally, add a small button
to close the dialog to help the user.

#345
## Description of change
For IIDX / SDVX, when the subscreen surface failed to capture, display
an error message, suggesting the user to patch the game as needed.
Prior to this change, the subscreen overlay just showed an invisible
window if this happened.
## Testing
Tested IIDX windowed / full screen, and voltex full screen.

## Description of change
Update ImGui to `v1.91.4`. We can't update to `v1.91.5` or newer just
yet because impl_spice depends on the old IO model of ImGui which got
removed in `v1.91.5`.
We also can't update the DX9 renderer right now, because at some point
overlay breaks in TDJ (and only in TDJ...)
Enable the new debug logging functionality in ImGui. Add a button in
overlay to toggle debug log window.
Fix some minor bugs spotted by the new ImGui debug log: mismatched API
calls, font loading issues.
## Compiling
👍
## Testing
In progress.
