TASImage support in gl-pad.
update comments
With new extended fonts we've broken some of eve functionality

(and probably other users of TGLFontManager). This fix tries to make everybody happy.
Also fixed error/warning messages in TGLFontManager and the bug - GetSize for TObjArray
does not return the number of entries.
10, not 0 as a font index.
DrawPixels - sketch implementation.
Fix TUrl bug inadvertently introduced in 728b157

URLs like "user@host" returned:

  GetUser() --> "" instead of "user"
  GetHost() --> "user@host" instead of "host"

This bug prevented PROOF from working at all.
Simplify DrawPixels' interface, add TGLPadPainter::DrawPixels' implementation.
1. Add a text transparency.

2. Add tutorials from cocoa - transparent object, transparent text, parallel coords with a transparency.
3. Rename ExtractRGB into ExtractRGBA, since it's what it does.
Ah, and don't forget retina displays.
