Neil Roberts ba068f6bc9 Fix the Cogl primitives for the GLES backend
The Cogl primitives broke for GLES 1.1 and 2 after the cogl-float
branch merge.

CoglPathNode was still being declared as GLfixed for the GLES backend
but it was being filled with float values so they were all ending up
as numbers < 1.

glDrawArrays was being called with GL_FIXED so this has been changed
to GL_FLOAT.

The scanline rasterizer had a leftover hardcoded ClutterFixed constant
to add a small amount to the height of each line.

struct _CoglFloatVec2 has been removed because it is no longer used
anywhere.
