Linear gradient fill.
Detailed description
Three modes are available:
In this mode the result angle will visually correspond the original setting, non regarding browser scaling duplication (so, for objects that do not have 1:1 proportion with the original figure, the gradient angle will correspond to the initial value due to internal calculations).
ObjectBoundingBox with angle value preservation(the second rectangle on the image)
In this mode, gradient vector is calculated with the preset angle, but the result gradient angle on the rendered page can be changed if the object proportion is not 1:1 in the browser. So visually the result gradient angle may not correspond to the original settings.
UserSpaceOnUse (the third and fourth rectangles on the image)
In this mode gradient settings are added by gradient size and borders/coordinates, and rendering is calculated within those borders. After that, the fill is executed on the element figure according to its coordinates. More about this mode at gradientUnits.
