/*
* Leaving attempt implementation of an argb cursor using alpha plane
* for the smi 501/502 under this ifdef for now. Maybe it will be fixed
* in a subsequent hardware revision.
* The problem is that the alpha plane will only work (that is, become
* visible) if alpha_plane_tl is set to top:=0 and left:=0.
* Also, if alpha_plane_br does not match panel dimensions, the alpha
* plane will be displayed tilled in the "first" row, with corruption on
* on all odd columns.
* Since setting the alpha fb_address works, to implement an argb cursor
* using the alpha plane, with the current hardware bugs, it would be
* required to:
* o allocate an offscreen area of pSmi->lcdWidth * pSmi->lcdHeight * 2
* o set statically tl/tr to 0,0,pSmi->lcdWidth-1,pSmi->lcdHeight-1
* o use alpha format 3 (argb 4:4:4:4), or alternatively format 1
* (rgb 5:6:5), and in the last case, a global 50% alpha is the
* best bet, and for the argb cursors being used at the time of this
* writing, they look correct, while 100% opaque looks wrong.
* o when positioning the pointer, first erase it from the offscreen
* area, then repaint it at the proper offset in the alpha offscreen
* area.
* .... argb software cursor works way better
* (There are some other alternatives, like using 8 bits indexed mode,
* but when using a global alpha value, instead of per pixel, most argb
* cursors will not look correctly, regardless of the alpha value, that
* should be from 50 to 100% transparency).
* But still there would be the problem of memory requiring a 128 bit
* alignment, what would require either moving the image in the memory,
* and/or some trick with the vsync pixel panning.
*
* Until the alpha layer is corrected in some newer revision (or removed?),
* it could be used as something like an alternate crt, that happens to be
* on top of the panel (and has 16 transparency levels).
