Memory leak on GlSurface resize

[IceReaper]

I am currently using the following nuget packages:

• Eto.Forms 2.5.2
• Eto.OpenTK 0.1.2
• Eto.OpenTK.Wpf 0.1.2
• Eto.Platform.Wpf 2.5.2
• OpenTK 3.2.0 (Same behavior when using 3.0.1)

I basicaly have my own layout engine attached, which reacts on window size changes and updates all elements in a PixelLayout container. Everything works so far, however when updating GlSurface.Size additional memory is consumed which is not freed anymore. The impact seems larger on larger sizes.

When just commenting out the assignments of the size, the memory leak is gone.

When using any other control, for example a button, this problem is gone too, so its tied to GlSurface only.
