-design (+ usage)
+horny desktop pet thing.
 
-(this is for now just a design document and not describing the actual program.)
+you need sdl3 to build it.
+i have not tried cross-compiling to windows yet.
 
-slutpet makes use of s7 scheme as a scripting language.
-(this, by the way, is why the program takes a weirdly long time to compile --
-s7.{c,h} contain the entire s7 scheme interpreter, over 100,000 lines.)
-if you don't know scheme,
-   a) don't worry, it's pretty simple, and
-   b) sorry in advance.
+i think it's probably best to use some sort of extension language.
+i want people to be able to create their own pets without having to
+figure out how to recompile.
 
-c source files:
+run it with `SDL_LOGGING=app=debug ./slutpet` for verbose logging
 
-sp.c:	main entry, exit, event/render loops
+file layout:
 
-a pet is implemented by setting the variable 'pet' to
-an alist (is this the correct term?) which contains some values.
-setting the pet variable should handle this automatically,
-but various hooks can then be set, which will be executed
-whenever a certain event has happened.
+dat.h - data structure header
+fns.h - functions and macros header
 
-list of variables:
-pet:		the pet that the program will use. this is a list of cons that define the pet.
-		TODO: maybe this should be a macro that sets other variables.
-
-pet-name:	string containing the pet's name.
-
-list of hooks:
-pre-init-hook:	before anything has happened at all; right after s7 has been initialised.
-		this is also before any init files have been read
-post-init-hook:	when the window has been set up and things are ready to happen.
-		the current pet should be set and initialised by this point.
-tick-hook:	every program tick. the pet's drawing information should be set
-		here so it can be rendered.
-TODO: figure out what to do about event hooks
-pre-quit-hook:	the program is about to exit, no de-init things have been done yet.
-post-quit-hook:	everything (except, obviously, the s7 interpreter) has been de-initialised.
-
-list of functions:
-(load-image path):	set up a new image, with the data taken from the given path.
-	    		this will return the a list of cons pairs with the image data,
-			in a form that can be used in the pet variable.
-(free-image image):	free heap-allocated data in image.
-
-list of c-types:
-pixmap:			the data created from stb-image.
