Set default framebuffer

After detach textures must set the default buffer again.

Also checked the number of samples, not only framebuffer.

Fix opacity change when drawing

When draw a stroke with a color with opacity < 1.0, there was a opacity change when finish stroke.

This was related to the blend pass that was used, so the drawing in fast mode must pass through the temp framebuffer to get same alpha values in blend.

New MSAA macros

Define macros for cleanup code.

Cleanup: Remove redundant code

Fix error introduced in previous commit

The macro used was wrong

Merge branch 'blender2.8' into greasepencil-object

Initialize selection alpha

There is a problem with this value for old 2.7x files, so the value is set to 1.0 when the file is from previous versions.

The initialization is done in weighttype section because this is a safe checking for old files and it is a related parameter.

Cleanup: Define macros for GP modes

Define new macros for checking grease pencil object mode to cleanup code.

Fix error in default gp object after delete

If delete the gp object and it is assigned as default scene gp object, must be cleared.
