The changes are:
- The shader now is passed as a parameter of the batch `draw` method (batch.draw(shader)). Since the batch always has to set a shader before drawing;
- The batch methods to specify a value to a uniform have been removed. Uniforms are parameters of the program (here called shader). If you change a uniform, it changes in all batchs that use the same program;
- New methods were added to set uniforms by the shader;
- The `batch.program_set_builtin` was removed. It is a duplicate of `program_set` but without a shader object. We need the shader object to configure the uniform;

This allows gizmo groups to store properties in the tool.
This makes sense for gizmo options which only control gizmo display and
don't control operator execution.
Unlike similar kinds of properties,
this isn't accessible via the gizmo-group-type instance.
For now the it's only stored in the workspace tool as can be done for
operator properties, so each instance doesn't have different settings
which would be confusing from a user perspective and complicate access
from the top-bar.
Later we could add gizmo-group properties if needed.
Terms get/set don't make much sense when casting values.
Name macros so the conversion is obvious,
use common prefix for easier completion.
- GET_INT_FROM_POINTER -> POINTER_AS_INT
- SET_INT_IN_POINTER -> POINTER_FROM_INT
- GET_UINT_FROM_POINTER -> POINTER_AS_UINT
- SET_UINT_IN_POINTER -> POINTER_FROM_UINT
Maybe it's still early to set the new drawing api for python.
But joining these two modules is an initial step.
```
>>> gpu.
matrix
select
types
```
```
>>> gpu.types.GPU
Batch(
OffScreen(
VertBuf(
VertFormat(
```
The creation of a new offscreen object is now done by the `GPUOffscreen.__new__` method.
