|
Working :
|
|
|
|
|
* Unaccelerated : Depth 8, 15, 16 and 24 are ok. I tested them upto
|
|
|
|
|
1280x1024 only as my monitor don't support higher modes.
|
|
|
|
|
* Endianess clean, thanks to Romain Dolbeau <dolbeaur@club-internet.fr> for
|
|
|
|
|
helping me debug this.
|
|
|
|
|
* HW cursor.
|
|
|
|
|
* ShadowFb.
|
|
|
|
|
* Full 2D Accels.
|
|
|
|
|
- Sync.
|
|
|
|
|
- Pixmap cache.
|
|
|
|
|
- Offscreen pixmaps.
|
|
|
|
|
- Clipping.
|
|
|
|
|
- Screen to screen copy.
|
|

|
* Appian J2000 second head initialization.
|
|
|
|
|
* Xv : Hardware video scaler :
|
|
|
|
|
- Needs checking on a big endian machine.
|
|
|
|
|
- Needs acceleration to work - there is a hardware bug in YV12 mode.
|
|
|
|
|
- Support both dual head and single head, trough gamma or permedia3.
|
|
|
|
|
- NOTE: depth 15 and 16 currently broken as I can't figure out the
|
|
|
|
|
colorKey equation. From the docs it needs to be padded to 8bits per RGB,
|
|
|
|
|
but that doesn't seem to work either. FIXME.
|
|
|
|
|
- Attributes are :
|
|
|

|
|
|
|
|
- Solid & Dashed Lines are not possible on glint hardware.
|
|
|
|
|
- 8x8 Color Pattern Fill is almost never used.
|
|
|
|
|
- Clipping needs cleaning up.
|
