| 1341 | * screenInfo.screens[n]->width/height added up. "screen" is ScreenRec, not |
| 1342 | * output. |
| 1343 | * |
| 1344 | * Coordinate systems: |
| 1345 | * - relative events have a mask_in in relative coordinates, mapped to |
| 1346 | * pixels. These events are mapped to the current position±delta. |
| 1347 | * - absolute events have a mask_in in absolute device coordinates in |
| 1348 | * device-specific range. This range is mapped to the desktop. |
| 1349 | * - POINTER_SCREEN absolute events (x86WarpCursor) are in screen-relative |
| 1350 | * screen coordinate range. |
| 1351 | * - rootx/rooty in events must be be relative to the current screen's |
| 1352 | * origin (screen coordinate system) |
| 1353 | * - XI2 valuators must be relative to the current screen's origin. On |
| 1354 | * the protocol the device min/max range maps to the current screen. |
| 1355 | * |
| 1356 | * For screen switching we need to get the desktop coordinates for each |
| 1357 | * event, then map that to the respective position on each screen and |
| 1358 | * position the cursor there. |
| 1359 | * The device's last.valuator[] stores the last position in desktop-wide |
| 1360 | * coordinates (in device range for slave devices, desktop range for master |
| 1361 | * devices). |
| 1362 | * |
| 1363 | * screen-relative device coordinates requires scaling: A device coordinate |
| 1364 | * x/y of range [n..m] that maps to positions Sx/Sy on Screen S must be |
| 1365 | * rescaled to match Sx/Sy for [n..m]. In the simplest example, x of (m/2-1) |
| 1366 | * is the last coordinate on the first screen and must be rescaled for the |
| 1367 | * event to be m. XI2 clients that do their own coordinate mapping would |
| 1368 | * otherwise interpret the position of the device elsewere to the cursor. |
| 1369 | * However, this scaling leads to losses: |
| 1370 | * if we have two ScreenRecs we scale from e.g. [0..44704] (Wacom I4) to |
| 1371 | * [0..2048[. that gives us 2047.954 as desktop coord, or the per-screen |
| 1372 | * coordinate 1023.954. Scaling that back into the device coordinate range |
| 1373 | * gives us 44703. So off by one device unit. It's a bug, but we'll have to |
| 1374 | * live with it because with all this scaling, we just cannot win. |
