A few visual improvements requested on Discord:
1. Use a configurable LOD to draw the outline wireframe, defaulting to LOD 1
2. Draw subsystem names with a dark outline to make them more visible
3. Draw the subsystem boundary boxes with thicker lines
* Adds the angle parameter to gr.DrawRectangle, allowing scripters to draw arbitrarily rotated rectangles.
* Revert "Adds the angle parameter to gr.DrawRectangle, allowing scripters to draw arbitrarily rotated rectangles."
This reverts commit b1a0480f32.
* Adds the angle parameter to gr.DrawRectangle, allowing scripters to draw arbitrarily rotated rectangles.
* fix wrong vertex position for unfilled rotated rectangles
* Adds a @param entry to gr_rect explaining the angle parameter.
* Attempt to fix operations with int to float conversions.
* Fix parameters in documentation string
* Change NULL to nullptr to satisfy modern coding standards
* Trying to make code a bit cleaner
Since that function already has full support for UV scaling it makes
sense to unify the behavior in one function instead of having a separate
monochrome function that does weird things.
Also deprecates that function since all its use cases are now covered by
drawImage.
Thanks to the new material system, it's now possible to easily make the
2D functions independent of the underlying graphics API which allows to
reduce the size of the gr_screen 2D API.
