Fix crash in styles example when running with opengl graphicssystem

When drawing text using glyphs, the shader manager will select the
"MaskFragmentShader" which requires a varying called "textureCoords"
which is used to sample the glyph from the glyph texture. That's
fine, except when you try to use one of the pattern brushes or a
texture brush, because the src pixel fragment shader snippets for
those brushes also sample from a texture (the brush texture) and name
the verying they use "textureCoords" too. This led to textureCoords
being defined twice, which in turn caused a shader compile error
which then casued the seg-fault. This patch simply renames the
varying used to pass the coordinates for the brush texture so it
doesn't conflict.
