Virtualize GL matrix operations and use a client-side matrix when GL is indirect This is useful because sometimes we need to get the current matrix, which is too expensive when indirect rendering. In addition, this virtualization makes it easier to clean up the API in the future.

[cogl matrix] Support ortho and perspective projections. This adds cogl_matrix api for multiplying matrices either by a perspective or ortho projective transform. The internal matrix stack and current-matrix APIs also have corresponding support added.
