Engine:GFX:TODO

Work in progress list of things that needs to be fixed/implemented/refactored in the GFX and GFX.D3D assemblies.

Replace "grids" with a more generic line buffer.
Check behaviour of Device.FlushSprites, and possibly remove it in favour of letting the device decide when to flush.
Clarify what the font size is in gfx font description.
Add kerning.
Use font family cell heights instead of silly "o" measurement.
Should font generation be moved out of renderer to the UI and passed to the renderer as an in memory bitmap?
Tidy brush description conversion.
Pen and brush conversion: sort out cultureness. (What should the default culture be? Invariant?)
Introduce sprite colouring.
Clarify font description blur factor
Use FileLoader more - such as in fonts (ideally all file access should go through an IFileLoader).
Determine differences between RenderCache.ForceFlush and RenderCache.Flush
Check D3D.IFontTexture.BaseLine for correctness
Add support for resizing/extending font textures as needs require.
Support multiple atlases.
Remove magic numbers from D3D.TextureFactory + AtlasTexture.
