Misc: switch back to SDL Qt Quick and QML was an exciting experiment but it's definitely not enough flexible and easy to use for game development. Using SDL2 will let us focusing on our own drawing functions without any kind of overhead. While here, start massive cleanup.

+# ----------------------
+#
+# malikania_build_assets(inputs outputs)
+#
+# Create binary data as C++ arrays for inclusion in source code. Static assets
+# increases the executable size so use this when really needed.
+#
+# The macro iterates over the input data which can be any files and generates
+# outputs file in the form CMAKE_CURRENT_BINARY_DIR/assets/basename.hpp.
+#
+# The macro removes the extension from the filename and create a static array
+# with that name, thus you need to specify a filename that is compatible with
+# C++ identifiers!
+#
+# Correct:
+#   - myfile.png
+#   - startup_logo.png
+#
+# Incorrect:
+#   - useful-code.ogg
+#   - archive.tar.xz
+#
+# Note: this macro requires the target mlk-bcc (tools/bcc directory).
