Detailed Description

A cloud of points, each one with an individual colour (R,G,B).

The alpha component is shared by all the points and is stored in the base member m_color_A.

To load from a points-map, CPointCloudColoured::loadFromPointsMap().

This class uses smart optimizations while rendering to efficiently draw clouds of millions of points, as described in this page: http://www.mrpt.org/Efficiently_rendering_point_clouds_of_millions_of_points

Coordinates (x,y) are 2D pixels, starting at bottom-left of the viewport. Negative numbers will wrap to the opposite side of the viewport (e.g. x=-10 means 10px fromt the right).
The text color is defined by (color_r,color_g,color_b), each float numbers in the range [0,1].
