true if the matrix is compatible with an affine transformation matrix
1.0
Converts a #graphene_matrix_t to an affine transformation matrix, if the given matrix is compatible.
The returned values have the following layout:
|[<!-- language="plain" --> ⎛ xx yx ⎞ ⎛ a b 0 ⎞ ⎜ xy yy ⎟ = ⎜ c d 0 ⎟ ⎝ x0 y0 ⎠ ⎝ tx ty 1 ⎠ ]|
This function can be used to convert between a #graphene_matrix_t and an affine matrix type from other libraries.
