moved generic matrix code to uMatrix.pas
updated shader and client logic to use a mat4 rather than
ftransform or gl_ModelViewProjectionMatrix.
// !!!just testing!!!
// This is not GLSL 1.3+ compatible, as its using the compatibility profile!
uniform mat4 mvp;
varying vec4 tint;
void main()
{
gl_Position = mvp * gl_Vertex;
gl_TexCoord[0] = gl_MultiTexCoord0;
tint = gl_Color;
}
