Should we rename this UiTexture to match UiElement?

[mthiesse, 2017/04/21 15:05:12]

Done.

An element width is in meters; I think the parameter should be documented here.

[mthiesse, 2017/04/21 15:05:11]

Done.

texture_size_ so that it's not confused with UIElement's size.

[mthiesse, 2017/04/21 17:17:30]

Done.

Possibly GLuint for clarity?  This is what glGenTextures() returns.

Done.
