* Re-think colors.Tavian Barnes2011-12-141-29/+29
| | | | | | | | | Color is a property of light, and thus doesn't include information about transparency. But canvas pixels and object pigments represent a color and a degree of transparency. The new type dmnsn_tcolor/ TColor encapsulates that information. Also, fix the transparent shadow implementation.

|
* New dmnsn_new_thread() function.Tavian Barnes2010-05-091-145/+117
| | | | | | | Two advantages: first, waiters are guaranteed to wake if a dmnsn_error() cancels a thread. Second, the thread library is fully abstracted over by threads.{c,h} and progress.{c,h} now, though raytrace.c is still using pthread_create() directly.
* Clean up some unused variables.Tavian Barnes2010-05-091-3/+1
|
* New DMNSN_ARRAY_FOREACH() macro, faster than iterating with dmnsn_array_get().Tavian Barnes2010-05-081-7/+5

* Use C99 for loop initializers.Tavian Barnes2010-05-051-19/+16
|
* New dmnsn_malloc() function, and friends.Tavian Barnes2010-04-071-83/+35
| | | | | | I'm tired of checking for malloc failures everywhere, considering it never happens. So just bail out whenever it does. A lot of stuff is guaranteed to succeed if it returns now.
* Set errno on failures.Tavian Barnes2010-04-011-8/+18
