- Helper functions
- ================
- PtrSize getDataSectionSize()
- Get The size of all the texture data. header+data_section_size == file_size
- PtrSize getCompressedFormatSize(format)
- Get the size of the a compressed format
- UVec2 getLevelSize(width, height, level)
- UVec2 getSurfaceSize(data_compression, level);
- Given a data compression format and the level get the size that the data should
- be
- =============
- Sanity checks
- =============
- - Compressed format and no mipmap should issue a warning
- - Get the total size of the file, sub the header, calculate the size and check
- if they match
