The filter will now automatically rescale the parent stack into the next best power of two size. With this, even non-power-of-two sources can now be mipmapped semi-correctly.
To accurately support mipmapping even for npot textures, this feature would have to be built into OBS and OBS would have to stop refusing to create textures with mipmaps that are not a power of two in size. Almost all common Direct3D 11 (except Intel) are capable of npot mipmaps at full speed, while OpenGL usually depends on the GPU and Driver used.
The '3D Transform' filter now support mipmapping using the Linear generator. This results in smoother images when the shape is squished or distant, instead of a pixelated mess.
Changes the GS::VertexBuffer storage to be one continuous buffer that is properly aligned and is also now used for GS::Vertex. This halves the necessary memory, removes reallocation cost and removes the copy necessary to get things onto the GPU.

* Fixed the perspective mesh not filling the entire frame with the default settings.
* Changed the maximum range of 'Field of View' to 179 degrees instead of 180 degrees.
* Changed the direction the perspective camera looks at to +Z instead of -Z. This should feel more natural for users of other 3D programs.
* Changed the 'Position (Z)' default to 0.
* Added translation strings for 'Field Of View', 'Position', 'Scale' and 'Rotation'.
FOV for the perspective camera was previously set to 180° (or more) resulting in really small images. Also added proper rotation support with options to choose which axis to rotate first.
