incorrect column width calculation

[falkolab]

This expression is not correct when Width measured in dpi:

screenWidth = params.width || Ti.Platform.displayCaps.getPlatformWidth();
if (OS_ANDROID) {
        screenWidth /= Ti.Platform.displayCaps.logicalDensityFactor;
    }

Replaced with:

screenWidth = params.width || Ti.Platform.displayCaps.platformWidth/(OS_ANDROID ? Ti.Platform.displayCaps.logicalDensityFactor:1);
