Update texture coordinates for MyTriangle

https://moodle.up.pt/pluginfile.php/120308/mod_resource/content/7/TexTrianglesUL.pdf

Add torus primitive

Add default material

diffuse white

Add support for component's materials

Fix transformations parser

The parser expects a single child node for each type scale, rotate and translate, however the specification only says there must be at least one transformation instruction and doesn't set any limit or order.

Also, consider making the transformation parser flexible to parse inline transformations from components/component/transformation.

Add texture to Torus

Implement XML parser

• scene @Dannyps
• views @fabiodrg666
  • perspective (leave this one for latter)
  • ortho
• ambient @fabiodrg666
• lights @fabiodrg666
  • omni
  • spot (later)
• textures
• materials
• transformations
• primitives @fabiodrg666
• components

Investigate out of order erros

Several warnings saying elements are out of order. The scene still renders, which I think is not supposed

Components parser: Fix texture lengths

When the texture id is:

• none, the attributes length* are not required, thus don't show any warning
• inherit, the attributes are also optional. If omitted, used the same texture lengths as the parents

Investigate lack of light reflection in MyRectangle

For some reason the rectangle is grey (default colors) and doesn't reflect any light coming from the light source. The rectangle is on plane Oxy, therefore I set the normals for each vertice as (0,0,1), but this is probably wrong.

Review yas.dtd

I never worked with this kind of files, so @Dannyps this one is for you!
I have used some online XML validation tools. The syntax is OK now (related with #2), but the validators report several errors related with inner elements (and probably others, around 60 erros). For example our ambient tag is as below:

<ambient>
        <ambient r="0.5" g="0.5" b="0.5" a="1" />
        <background r="0.5" g="0" b="0" a="1" />
 </ambient>

The validator says The content of element type "ambient" must match "(ambient|background)?".. Perhaps the way to tell that valid child elements must be ambient and background tags is not correct?
