== DETAILS
These changes fall into a few broad categories:
1. Explicitly undefine things we want to re-define due to conflicts with
the version of devkitpro we're using
2. Clean up hex format specifiers to use `%lx` or `%lX` when working with
long integers
3. Move variables inside the ifdef they're used in to squelch "unused variable"
messages
4. Add parenthesis to make Wii U shader declarations stop complaining
And then there's a weird "misleading indent" warning that I fixed by just
rewriting a block of code to use a switch statement instead of if-then-else.
These changes work fine on Wii U, but we'll need to keep an eye on CI/CD to see
if other platform builds break.
can load *.slangp and *.slang files. since there is no runtime compiler,
precompiled shaders (*.gsh) need to be present next to each *.slang
source file.
