Reviewed by Antti Koivisto.

Source/WebCore:

Border issue is fixed when border width is less than 0.8pt

Border width is stored as unsigned. Border width (specified by
author) is converted into pixels and some times this pixel value
goes less than 1px. In this case, border width becomes 0px when
pixel value (double type) assigned to unsigned type.
Border width should not fall to 0px unless it is specified by
author.

Test: fast/borders/border-width-less-then-a-unit-of-pt.html

* css/StyleBuilder.cpp:
ApplyPropetyComputeLength class is replaced with 3 classes :
ApplyPropertyComputeBorderWidth, ApplyPropertyComputeTextSpacing
and ApplyPropertyComputeTransformOriginZ.

(WebCore::ApplyPropertyComputeBorderWidth::applyValue):
(WebCore::ApplyPropertyComputeBorderWidth::createHandler):
This class handles all width properties like border, outline,
etc. These all properties stores value in integer types.
Pixel value rounded of to 1px if value less than 1px and greater
than 0px.

(WebCore):
(ApplyPropertyComputeTextSpacing):
(WebCore::ApplyPropertyComputeTextSpacing::setValue):
(WebCore::ApplyPropertyComputeTextSpacing::applyValue):
(WebCore::ApplyPropertyComputeTextSpacing::createHandler):
This class handles all spacing properties like word-spacing,
letter-spacing etc.

(ApplyPropertyComputeTransformOriginZ):
(WebCore::ApplyPropertyComputeTransformOriginZ::setValue):
(WebCore::ApplyPropertyComputeTransformOriginZ::applyValue):
(WebCore::ApplyPropertyComputeTransformOriginZ::createHandler):
This class handles TransformOriginZ Property.

(WebCore::StyleBuilder::StyleBuilder):
ApplyProprtyComputeLength class usage changed with defined new
classes as per class definition.
