Bug Description

Per the EDID 1.3 specification, the correct and expected aspect ratios for Standard Timings are:
16:10
4:3
5:4
16:9

Under Standard Timings Supported, edid-decode.c contains 9 / 15 instead of 9 / 16 which results in incorrect output for this section.

EG: line 1057 should read:
case 0x03:
 y = x * 9 / 16;
 break;

But instead reads:
case 0x03:
 y = x * 9 / 15;
 break;
