Add CRT display filters 41ac56899d
Two optional display filters that recreate the look of a CRT screen, under Settings > Options > CRT Filter:
- Flat (crt-easymode): Lanczos sampling, brightness-adaptive scanlines, and an RGB aperture grille.
- Curved (crt-geom): barrel distortion, rounded corners, beam-profile scanlines, and a dot mask. Mouse input for gameplay is warped to match, so clicking on the curved image hits what it looks like it hits.
Both are ports of shaders distributed by the libretro project (GPL, like ZQuest Classic). The filter applies only to the game layer - menus, dialogs, and the pause-dimming overlay stay crisp and work as before. On the web version the game renders at full device resolution while a filter is active, so scanlines stay even instead of dissolving into moire.

Also, the text overlay (fps, game time, PAUSED) now scales with the game area, so it reads the same size at any window size.
Give the title screen an animated sword intro ca9cc641aa

The logo crawls up over a blue background instead of black, without its sword; the sword then thrusts in from the left with a rising woosh and slots home through the letters with a white flash and sfx on impact.
Apply the CRT filters to the cheat overlay layer 0deed9225c

The cheat/debug overlays - walkability, effect flags, hitboxes, and the debugger's sprite highlight - now render through the active CRT filter instead of being drawn crisp and flat over it. The layer is also skipped entirely while empty, which is nearly always, removing a fullscreen blend per frame even with no filter.

Bug Fixes

Mask the title screen logo until it enters the game viewport 2e74b33986

Children of the game layer are drawn straight to the backbuffer when no CRT filter is active, with nothing clipping them to the layer's on-screen rect - so the logo crawl (which starts fully below the viewport) painted over the black letterbox border at the bottom, and the sword thrust over the left one. Add an opt-in clip_to_parent flag that confines such a child to its parent's rect, matching what the shader paths already do by construction.

Combo/item editors not refreshing attribute metadata 201a205a40

When closing the new Script Setup popup, the attributes were not refreshing their metadata, wrongly requiring closing and reopening the dialog to update the metadata.
Error in 'Viewport Range' combo trigger help text de8c7079c4

It mentioned 'In View' and 'Out of View' flags, but these flags are actually named 'Req. On Screen' and 'Req. Off Screen'.
