People who make texture packs usually release them using a specific ID
(for instance SX4E01). Users who have a different version of the game
(like the PAL version SX4P01) then need to rename the custom texture
folder to match. This is a lot simpler than renaming every texture file,
as was required with the old texture format, but it's still something
that users can forget to do. To make that unnecessary, this change makes
it possible to use three-character region-free IDs for custom texture
folders, similarly to how game INIs can use three-character IDs. Once
most people have updated to Dolphin versions that include this change,
those who make texture packs will be able to name them with
three-character IDs, removing the need for users to rename anything.
- FileSearch is now just one function, and it converts the original glob
into a regex on all platforms rather than relying on native Windows
pattern matching on there and a complete hack elsewhere. It now
supports recursion out of the box rather than manually expanding
into a full list of directories in multiple call sites.
- This adds a GCC >= 4.9 dependency due to older versions having
outright broken <regex>. MSVC is fine with it.
- ScanDirectoryTree returns the parent entry rather than filling parts
of it in via reference. The count is now stored in the entry like it
was for subdirectories.
- .glsl file search is now done with DoFileSearch.
- IOCTLV_READ_DIR now uses ScanDirectoryTree directly and sorts the
results after replacements for better determinism.
There is no nice way to correctly "detect" the "used" memory, so we just say
we're fine to use 50% of the physical memory for custom textures.
This will fix out-of-memory crashes, but we still might run into swapping issues.
