[mkgmap-dev] DEM file and the block-size option

Hi Gerd,

I have seen this code. I think it is wrong to use the same option for 
tiles and index. Index can be very big regardless of tile size.

I noticed other problem. Please look at any *_mdr.img with block size 
16k. You will find a 3MB of zeroes between FAT and map data. I haven't 
found code, which calculates offset from beginning of file to start of 
MDR header, I think it is calculated wrong. It looks like offset 
increases with block size, which makes no sens - FAT records remains the 
same, regardless of block size.
