Subject: [PATCH] test: map URL to other directories
This allows to 'mount' the SDL source directory on http://localhost:8080/SDL.
This is useful for debugging emscripten applications in the browser.
Build SDL with "-gsource-map -ffile-prefix-map=/path/to/SDL:/SDL" to
configure the URL where the source code must be available.
