questions to your commit "wineps.drv: Allow for vertical text printing!"

[Wolfgang Walter]

Hello Aric,

I read commit 745e7c93c9042f62460f181daaa1f05645560b41 (wineps.drv: Allow for 
vertical text printing.) and I have some questions:

1) You added the parameter vertical to PSDRV_WriteSetFont() in ps.c but it 
remains unused. I think it isn't needed.

2) In PSDRV_WriteSetDownloadFont() in download.c you call PSDRV_WriteSetFont() 
with

(lf.lfFaceName[0] == '@')

for this new parameter vertical. I can't see why.

3) You added the parameter vertical to get_download_name() in download.c

You use it to add "_vertical" to its name if vertical is true. I can't see why 
the font needs a different name.

This will cause PSDRV_WriteSetDownloadFont() to download a font which is used 
vertically and horizontally twice. I can't see any reason why this could be 
necessary.

I think that

* PSDRV_WriteSetFont() should be changed back

and of course the callers, too (in builtin.c and download.c)

* get_download_name() should also be changed back

(and its call in PSDRV_WriteSetDownloadFont())

Regards,

Hello Wolfgang,

You are correct here.  These are artifacts of the original way I was trying to solve this problem which I failed to revert when I change to creating the vertical runs and doing all the work in download.c.

I will generate a patch to remove these.

This unfortunately is necessary because the escapement is different between the normal and vertical variations of the font. The only way I found for a font to be able to be both horizontal and vertical in a document is to download the font twice, once with each escapement.
