Merge all static and dynamic buffers to just one, "memory". Add a malloc function for dynamic allocations. Unify static allocation offsets into a "config" buffer containing scene setup (number of paths, number of path segments), as well as the memory offsets of the static allocations. Finally, set an overflow flag when an allocation fail, and make sure to exit shader execution as soon as that triggers. Add checks before beginning execution in case the client wants to run two or more shaders before checking the flag. The "state" buffer is left alone because it needs zero'ing and because it is accessed with the "volatile" keyword. Fixes #40 Signed-off-by: Elias Naur <mail@eliasnaur.com>
