because the mipmap was not being refreshed. Also this will be problematic
to support when I add tile/mipmap cache, so would not rather not try to.
Can be added back afterwards if someone wants to make it work.
* Fixed up RNA and UI
* Brought back 'Save' and 'Clear' operators (in the little triangle menu in
environment map properties)
* While I was at it, noticed that environment maps were only using 8bit
colour, changed it to use full 32bit float instead for proper HDR colour etc,
so environment map reflections have the correct colour range

This fixes [#20904] Environment Map does not render; also missing panel
Used approach with creating DerivedMesh for curves whet they've got such modifiers.
Available modifiers are: array, edge split, mirror, solidify, subsurf.
rendering.
RE_BlenderFrame() and RE_BlenderAnim() are Blender's internal
top-level rendering API functions for a single frame and a series of
frames, respectively. These functions rely on global variables to
keep render pipeline states. Freestyle's stroke rendering was also
using RE_BlenderFrame to render a temporary scene of stroke meshes.
These nested calls of the top-level rendering API functions were
causing broken render pipeline states and eventually led to a crash.
This commit is intended to fix the issue, by introducing an rendering
API function RE_RenderFreestyleStrokes specifically used for stroke
rendering in Freestyle. The new function does not do anything with
regard to the global variables in the rendering API implementation.
* Remove the manual OSA method but rather pass on derivatives to the
textures. This means that at the moment e.g. the bricks node is not
antialiased, but that image textures are now using mipmaps. Doing
oversampling on the whole nodetree is convenient but it is really
the individual textures that can do filtering best and quickest.
* Image textures in a texture node tree were not color corrected and
did not support 2d mapping, now it's passing along shadeinput to
make this possible. Would like to avoid this but not sure how.
* Fix preview not filling in all pixels when scaling or rotating in
the texture nodes.
Transparent strokes are rendered by means of transparent vertex colors.
To make this possible, Blender's internal renderer has been slightly
extended to allow transparent vertex colors. When Material::vcol_alpha
is non-zero, the renderer takes MCol::a into account.
Implementation note: this was done by giving each Render a slot number,
and for every slot a new Render will be created. Not sure if this is
ideal, but it ensures that all passes, render info, etc are separate so
you can also compare render layers and passes, in 2.4x only whatever it
was currently displaying was backed up.
* Bugfix, rasterization was shifted half a pixel.
* Remove scaling of bias by render size, there is something to be
said for doing to compensate for lower shadow buffer xy resolution,
however the z-resolution does not change and this seems to have a
larger effect.
* Remove clamping of filter size by soft factor. Now it is clamped to
1 pixel instead to ensure there is some AA. Why this was done this
way is not clear to me, however on decreasing shadow buffer resolution
this would change the softness by increasing the filter size.
Disables save buffers and full sample when render border is turned on (render doesn't work otherwise because save buffers doesn't support border rendering).
- triangulating non planer quads is needed to resolve some artifacts however this also ends up triangulating most faces in - Suzzane subsurf level 4 for eg.
this check could be tuned for better performance but for now skipping it is useful for test renders.
