Missing info on pr_trianglefan in docs

[Appsurdgames]

Description

On the manuel page about draw_primitive_begin, the constant pr_trianglefan is mentioned in the table, but the corresponding picture doesn't show what it does.

On the manual page about vertex_submit, the constant pr_trianglefan is again not shown in the picture, but it is also missing in the table.

Also, draw_primitive_begin lists the limitations of Windows, Xbox, and HTML5, but vertex_submit and draw_primitive_begin_texture don't. The manual ought to mention the same limits -- or the difference if there is one -- on the corresponding pages.

(triangle fans look like triangle strips but each triangle share the first vertex. but trianglefans are a pretty unsupported primitive type all over the place—if gm gets a full implementation of webgpu for gmrt then there wont even be a trianglefan option cause its not in the spec at all. if i were gm i would update the manual to suggest those people looking to make a fan get comfy with a strip or list instead)

[YYBartT]

Added an example of pr_trianglefan to the picture. Also added a warning note to pr_trianglefan in the Primitive Type Constant table to mention that it may not be supported on some platforms as well as a note on the vertex_submit and vertex_submit_ext pages to explain that these functions will convert the data in the vertex buffer if the submit is done using the pr_trianglefan primitive type (i.e. vertex_submit(vb, pr_trianglefan, tex)).
