WM: new offscreen window draw method to replace all existing methods. For Blender 2.8 we had to be compatible with very old OpenGL versions, and triple buffer was designed to work without offscreen rendering, by copying the the backbuffer to a texture right before swapping. This way we could avoid redrawing unchanged regions by copying them from this texture on the next redraws. Triple buffer used to suffer from poor performance and driver bugs on specific cards, so alternative draw methods remained available. Now that we require newer OpenGL, we can have just a single draw method that draw each region into an offscreen buffer, and then draws those to the screen. This has some advantages: * Poor 3D view performance when using Region Overlap should be solved now, since we can also cache overlapping regions in offscreen buffers. * Page flip, anaglyph and interlace stereo drawing can be a little faster by avoiding a copy to an intermediate texture. * The new 3D view drawing already writes to an offscreen buffer, which we can draw from directly instead of duplicating it to another buffer. * Eventually we will be able to remove depth and stencil buffers from the window and save memory, though at the moment there are still some tools using it so it's not possible yet. * This also fixes a bug with Eevee sampling not progressing with stereo drawing in the 3D viewport.
