Major rework of mesh handling in Blender exporter
All of the preprocessing has been moved out of the MeshExporter class and
into a utility function. This should make it easier for other exporter
classes to use meshes.

Move most properties from exporters to the relevant types
These properties pertain to the things being exported and should retain
their values between exports. It's getting especially difficult to
specify object-specific properties when exporting an entire scene.

Rearrange GLSL qualifier parsing
GLSL 4.20 allows qualifiers to be in any order so there's no sense to
enforce a particular order here. Always output them in a compatible
order though.

Have Object provide an identity matrix from get_matrix
It's often useful to have static geometry in a scene directly as an Object
without creating an instance. Many features such as Z-sorting and culling
require a matrix to be available.

Explicitly define the number of mipmap levels in textures
Storage() no longer uses the minification filter to decide whether to
allocate mipmaps or not. That functionality has been moved to image(),
specifically the version taking a Graphics::Image.

Reorder functions in dependency order
Otherwise the inliner might inline a function to a point before its
original definition. This can break references to other functions
declared after the inlining point, causing the unused function eliminator
to eventually remove them.

Fix matrix interpolation parameter calculation
With an x87 FPU and compiler optimizations enabled, the code could end up
taking arccos of a value very slightly larger than one. This would result
in a NaN and destroy the matrix contents.

Fix a bug in ProgramData when all uniforms in a block are removed
Program blocks continued using the previously generated uniform blocks,
but because the uniform values were removed the blocks were not updated
anymore.

Refactor AnimationPlayer ticking
It's not more consistent between single and stacked animations. There
shouldn't be significant performance penalty since the animation states
would be freed upon removing the target anyway.

Fix a stale pointer issue with Animation
Now that keyframe information is stored in a vector it's no longer
guaranteed that pointers to them stay valid after push_back. Re-link
all TimedKeyFrames if the vector gets reallocated.

Use an explicit material slot name in RenderPass
The previous method of overriding materials with pass name seemed a
bit too hacky to my liking. This is more in line with how overriding
textures works.
The Blender exporter now expects the base technique to have a material
slot "surface".

Add a function to remove uniforms from ProgramData
It may be beneficial to revert to a Technique's default value and its
associated buffers instead of explicitly setting the same value in an
ObjectInstance's private ProgramData.

Allow direct access to AnimatedObject's ProgramData
The animation-related set_uniform interface was already public so there
isn't any good reason to not allow full access. This also makes trivial
customization easier as subclassing is not needed.

Use different heuristics for applying shader data
Since later shdata can override values from earlier ones, the stack must
be replayed even if items are only removed. However we can detect if the
exact same items are added back as might happen when multiple objects
using the same technique are rendered in succession.

Rename imported interface variables in InterfaceGenerator
Doing it as a separate pass caused trouble when a variable was accessed
both with passthrough and explicitly. Two input variable declarations
were generated and only one of them was linked to the output variable of
the previous stage, leading to the output variable being removed.

Split the interfaces from singlepass.glsl to a separate module
Sometimes it's desirable to make a fully custom shader but still use the
common interface. It's also likely that I'll add other types of standard

Check for maximum number of samples
This makes it more apparent what the error is if a too large sample count
is requested. Otherwise it would result in an "incomplete attachment"
error from the framebuffer object.
