The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.
In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.

... even though 3x3 feels better.
This is a compromise to get core profile up & running sooner. Eventually I'd like to finish the original 3x3 plans, but this commit will let us get on with other tasks.
External API stays (almost) the same. Our GLSL shaders can use this without any changes.
Part of T49450 and T51164
These functions mark the beginning and end of 3D drawing, causing the matrix API to use our own implementation instead of legacy OpenGL.
Part of T49450
Look up "name[0]" when asked for "name", since that marks the beginning of the array.
We're comparing to the name stored in ShaderInterface which comes from glGetActiveUniform.
This eliminates tons of glGetUniformLocation calls from the drawing loop. Vast majority of code can keep making the same function calls. They're just faster now!
- Batch_Uniform*
- immUniform*
- gpuBindMatrices
- and others
- builtin uniforms match what Blender needs
- set input counts in struct (stupid mistake)
- look up uniforms by name
- look up builtin uniforms by enum
- check attrib/uniform locations for error
Same as MEM_SAFE_FREE macro,
checks for NULL, runs free then sets NULL.
Blocks of code that do this many times are noisy and likely
errors here wouldn't be noticed immediately.
Also NULL's static vars which were being left set.
Problem was an edge case where vertex_ct logic and draw logic disagreed on how many dividers to draw.
Fix: copy draw logic to earlier vertex_ct
I also skip any drawing or setup if vertex_ct = 0, and set color attribute only for each line's provoking vertex. Small optimizations but these things add up.
We can not re-use anything for such pools, because we will know nothing about whether
the main thread is sleeping or not. So we identify such threads as 0, but we don't
use main thread's TLS.
This fixes dead-locks and crashes reported by Luca when doing playblasts.
This removes MAX_STORAGE, MAX_BUFFERS, MAX_TEXTURES, MAX_PASSES limits.
Actual memory saving isn't so important, it just means we don't need to
manually bump these based on changes to engines.
The issue was caused here by usage of deprecated GL_CURRENT_PROGRAM
which was returning rubbish value.
Now we use imm API and create vertex format prior to immBindProgram.
This made us required to have some sort of state passed from setup
function to actual drawing.
