Orientation: planning

[easytarget]

I want to add 'orientation' options;

This enables rotated text, and effects such as mirroring.

• flip (bool) : mirror about the horizontal axis
  • simply manipulate the glyph before adding to character framebuffer
  • affects the vertical alignment operation for baseline, flips top and bottom
• mirror (bool) : mirror about the vertical axis
  • reverse the character print order
  • manipulate the glyph before adding to character framebuffer
  • flip left and right horizontal alignment
• twist (bool)
  • hardest
  • change the print direction
  • change the alignment operation (this could get complex)
  • manipulate the glyph before adding to character framebuffer (which needs x/y dimensions adjusted to suit)

Changes applied to the alignment by flipping and mirroring, plus the axis swap from twist need to affect be reflected in returns from the rect() method (but size should be unaffected? I need to think about whether width and height should be swapped when twist is applied?, humm...)
