gitignore: ignore Bitmap_VS_SVG.svg

[gucio321]

as mentioned in #98 (comment), #97 (comment) This image is often added in our PRs. I think that, as it is autodownlaoded it should be ignored by git entirely

[slayoo]

sounds good (although probably even better solution would be to download it to some out-of-repo temporary folder?)

Probably yes. I'd even say that this downloading code should not be there. Instead, we should be able to include images like in usual markdown with ![tag](URL) (potentially causes random test crashes)

[slayoo]

the original idea of downloading it on the fly was related with the thesis-in-a-single-file premise...
this still seems to be the only external file needed for the whole project, hence it is tempting to retain it this way

if we want to keep the whole thesis in a single file (which is nice for simplicity, especially given that this is meant to work as a template, and we have little control on how it will be disseminated), we could also include the SVG contents within the notebook (e.g., with the )?

But on the other side, if we'd keep the practices of not repeating the code, I think that refering the image with a link sounds better.
This file in fact is not "needed" in the sense that we don't need to ship it with the notebook - it is publically available and in fact should be handled internally by quarto.

[slayoo]

but is there a way to handle the download by Quarto?

[gucio321]

Yes! After some testing turns out that the Wikipedia is an issue.
WHen doing e.g. this:

![test1](
https://upload.wikimedia.org/wikipedia/commons/6/6b/Bitmap_VS_SVG.svg)

 (StatusCodeException (Response {responseStatus = Status {statusCode = 403, statusMessage = "Forbidden"}, responseVersion = HTTP/1.1, responseHeaders = [("content-length","126"),("content-type","text/plain"),("x-request-id","6a25f86b-7939-47b2-80a4-e163e8e9cee7"),("server","HAProxy"),("x-cache","cp3081 int"),("x-cache-status","int-tls"),("x-analytics","")], responseBody = (), responseCookieJar = CJ {expose = []}, responseClose' = ResponseClose, responseOriginalRequest = Request {
  host                 = "upload.wikimedia.org"
  port                 = 443
  secure               = True
  requestHeaders       = []
  path                 = "/wikipedia/commons/6/6b/Bitmap_VS_SVG.svg"
  queryString          = ""
  method               = "GET"
  proxy                = Nothing
  rawBody              = False
  redirectCount        = 10
  responseTimeout      = ResponseTimeoutDefault
  requestVersion       = HTTP/1.1
  proxySecureMode      = ProxySecureWithConnect
}

But when trying to download some "simply" hosted image:

![test2](https://promat.agh.edu.pl/posts/115858349789616_1398296795672056/main_image.jpg)

It works fine.

To download from wikipedia, we probably should either use some dedicated bot api or force quarto to set it's user-agent to something like Mozilla/5.0 (like the current code does)
