Let's talk about Draw Rectangle, because I actually solved that problem in the wild.
draw::rectangle(destination,rect16(0,0,99,99),color_t::purple);
The draw class acts on "draw destinations" which are like canvases. The first argument is always this target. In this case destination above
The second argument is always the location(s) of the object to be drawn - in this case, a rectangle with unsigned 16 bit coordinates. (my lib uses rect16 for that, or srect16 for signed)
gfx/include/gfx_positioning.hpp at master · codewitch-honey-crisis/gfx · GitHub[^]
Before I built the drawing operations, I built up the position elements, as shown in that file.
Rectangles can be normalized, or denormalized, and have a fundamental orientation in my libraries.
For draw::rectangle, the orientation is irrelevant, so rect16(99,99,0,0) would be equivalent to that routine.
rect16 newrect = myrect.normalize();
myrect.normalize_inplace();
That will ensure the rectangle's dimensions are intelligible to this routine. Some routines honor the rectangle orientation, such as draw::bitmap, which can flip the bitmap on the x and/or y axis.
I built this constructively. Or at least, i'd get to the point in the drawing code where I needed, say a rectangle element, and then I went back and designed the positioning elements as exhaustively as I could at the time.
I then continued where I left off with my new toolbelt of rects, points, sizes and paths.
Doing this I've managed to create a library that has survived several years with hardly any major architectural changes, and very few breaking code changes, none recently.
I was careful. I was fastidious. And one thing I did that I don't normally do is I designed for completeness rather than for use cases, primarily because I didn't have all the use cases my end users (including me) would use it for in front of me. So I envisioned a model of completeness and coded to that.
Take a look at that positioning code and you'll find I covered pretty much every eventuality.
Like I said, I normally don't code that way, but in this case, breaking my rule served me well.

Entered the living room this morning and I immediately noticed the giant splash of water near the back door.
The rain is seeping through the ceiling through a leakage that seems to be about a meter wide 
It's been raining for about a month, but never had this problem until last night.
This sucks big time! (not quite the expletives I uttered this morning, but let's keep it civil)

I know it is not the best answer, but if water only drops from the upper side, be happy.
It could come as a wave through the doors, bringing mood, oil from the crashed cars and many other things (like fecals, dead animals or similars).
We have had the strongest rain week of the last years, the basements of most houses got full of water, a colleague lost his car, another one had to be evacuated... luckily I wasn't directly affected
Damned extreme weather

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

Yeah, could be worse, although floods like that don't really happen where I live (well, not since "the disaster" of '53).
We've had the wettest May ever, so it's kind of weird it only started leaking now.

Luckily no floodings at the Mosel river where we are on holiday at the moment near Traben-Trarbach, also the weather is fine since our arrival last friday.

Could be worse - if we notice a puddle on the floor somewhere, it's usually one of our cats.

That was my first thought too.
Not sure how cat going pee pee is worse than a structural defect in your house though

Cat pee has a really strong smell, and it's very hard to get rid of. I bought a new set of motorcycle waterproofs, and before I got a chance to use them one of our cats managed to pee on the inside. Even jetwashering didn't help - I binned the set and got a new one ...

Sheesh, I thought you were talking about a memory leak in a program!😳

i'm sure there's an ointment to help with leakage.

Oh! You're talking about the roof. Sorry, I thought it was something ... medical. Yeah, we'll go with that.

Had something similar happen due to a faulty vent on our roof, and near sidewise rain - I live in a really rainy region.
It flooded the INSIDE of our walls and was running through the doorframe of our coat closet. So that was fun.
I don't envy you, because I've been there. I do wish you the best of luck, and I hope it's an easy fix. It was in our case, relatively because we caught it before it did any expensive damage.

I woke up this morning with lots of water just outside my bedroom window. Then I remembered we are on a cruise ship.

That sucks. Take a look directly above the leak and to three or four yards (meters) on either side of the leak. Look for any beams sticking out and seal around these beams. This is what finally solved a similar leak in my house.

Why do people go out of their way to answer questions that we know should be in a different forum with people we know abuse the system? Like, what's the impulse to be the sucker? Not really referring to peeps we know who don't do nothing but abuse the system over and over, but to those who blatantly do not care and 100% of their posts is nothing but questions in the lounge.
And sure, we've all done it at times (myself included). And at times I'll attempt to help if there's no forum suited for the query in question that I know of at the time of replying and it's someone I know. Like for instance, Sander just had a networking question and only now do I realize there's a hosting and servers forum. Oops. So, I guess I'm a hypocrite. 
But, we know Sander and know he's not intentionally breaking the rules. Can't say that for some in the lounge (won't mention his name). So, why? Surely, doing nothing but answering tech questions to people exploiting this fact is not a dev's idea of being "social"?

Not to mention there is still someone trying to answer his questions in appropriate forums...

I think it's partly because folks know their post will be seen pretty much immediately in The Lounge.

^ This.
It's not laziness, it's just increasing the odds someone that possesses knowledge on some obscure/very specific topic will see it and offer a response.
Who in his right mind regularly looks at all the forums?

I think it is nothing more than people liking to help others. Sure, they should refer the questioners to the appropriate forum, but in many cases it's much easier to answer the question.

And that's noble, in theory. But, if they liked it that much it's just as easy to go to a forum to help keep them active. Side note, it's also called enabling and liking the helping so much they're willing to be blatantly exploited and manipulated.

I agree with Dan.
CP is somewhat of a free form learning and teaching forum.

I have an idea/suggestion/solution: it shouldn't be too difficult to give a select few (editors, protectors, whatever) a tool to move a thread to the appropriate forum, eventually informing OP of the change of venue. Not only would this free the lounge of the occasional misplaced thread, it might also breathe life in other forums. In particular, the forum you mentioned, "hosting and servers", hasn't seen a new message since October of last year.
