What about making MAX_WIDTH and MAX_HEIGHT runtime-configurable - would that be possible (for stack allocations the Mesa code then has to depend on |alloca()|) ?
Probably do-able, but a lot of work.
Depends... if |alloca()| can safely be used on all platforms supported by Mesa then this should be no problem to implement. Alternatively the code could simply assume that the C compiler supports the C++ feature (BTW: Is this supported in C99, too ?) that an array can be dynamically sized at declaration (however that's less portable).
I don't want to create a dependency on C99's variable length arrays. I'm also leary of alloca() since it's not in POSIX.
"grep MAX_WIDTH src/mesa/*/*.[ch] | wc" shows there's about 160 occurances of MAX_WIDTH that would have to be changed for dynamic allocation. A lot of work.
