Add VSync and fullscreen settings, fix swap chain resize and revert lighting changes
- Add VSync and Exclusive Fullscreen toggles to the graphics settings menu - Rewrite D3D11 swap chain to use DXGI flip model with tearing support - Fix black screen on resize by creating new swap chain instead of ResizeBuffers - Revert conditional lighting optimization in Level::setTileAndData back to unconditional checkLight - Revert deferred lightGaps flagging in LevelChunk::recalcHeight back to immediate lightGap calls - Add SWF/ARC editing tools used to add new UI checkboxes

/**
|
||||
* Rebuilds a MediaWindows64.arc archive file by replacing specific SWF files
|
||||
* with updated versions from disk.
|
||||
*
|
||||
* Usage: RebuildArc <arc_file> <media_dir> [file1.swf file2.swf ...]
|
||||
*
|
||||
* If no specific files are given, replaces all SWF files found in media_dir.
|
||||
* The arc format is Java DataOutputStream style: big-endian ints, modified UTF-8 strings.
|
||||
*
|
||||
* Archive format:
|
||||
* int: numberOfFiles
|
||||
* For each file:
|
||||
* UTF: filename (prefixed with '*' if compressed)
|
||||
* int: offset into data section
|
||||
* int: filesize
|
||||
* Raw file data follows the header
