Patch naming scheme for Mesa.patches:
-------------------------------------

For patch file names, use characters from this ASCII subset:
[a-zA-Z0-9_-.].

This precaution is esp. important, if you build nx-libs without having
the quilt utility available in the build environment. This is mostly true
for non-Debian-based systems.

Patch numbering scheme:
-----------------------

The patch naming scheme is about ordering patches by names and
categories. All patches shall be prefixed with a number:

0xxx: Mesa upstream backports
1xxx: Patches that might be interesting for Mesa upstream
2xxx: Distro specific patches (not applicable here, probably)
3xxx: Security / CVE fixes for Mesa (probably obtained from upstream)
4xxx: Patches that are needed to make Mesa work/build with/against nx-libs
5xxx: Patches that silence compiler warnings

The "series" file within the Mesa.patches directory defines the order of
patch application.

The patch names in the "series" file do not necessarily need to be in
alpha-numerical order. Patch application order is about code and
functionality, That is, patches in one category are allowed to depend
upon patches in another category, even if the subsequent digits are not
strictly ascending.
