    <p>Figured it out... here is the correct code in case it helps someone else</p> <p>Note that I removed the references to vid.xratio and vid.yratio... what I do instead, is after calling Matrix::Ortho on the projection matrix, I do:</p> <p>Matrix::Scale(projMatrix, vid.xratio, vid.yratio, 1.0f);</p> <pre><code>const byte picVerts[] = {0, 0, 1, 0, 1, 1, 0, 1}; // // DrawPictureSize // // Draws a picture on the 2D screen, width and height specified. // // Note: 'Set2D' must be called before this! // void DrawPictureSize(float x, float y, float width, float height, float scalex, float scaley, Vector::vector_t *upVec, byte alpha, Texture::texture_t *texture, int halignment, int valignment) { if (!texture) return; float matrix[16]; Matrix::LoadIdentity(matrix); width *= scalex; height *= scaley; float angle = U_Rad2Deg(atan2(upVec-&gt;y, upVec-&gt;x)) - 90; float xalign = 0; float yalign = 0; // Move into position if (halignment == Font::HALIGN_CENTER) xalign = width/2; else if (halignment == Font::HALIGN_RIGHT) xalign = width; if (valignment == Font::VALIGN_CENTER) yalign = height/2; else if (valignment == Font::VALIGN_TOP) yalign = height; // Move into position Matrix::Translate(matrix, x - xalign, y - yalign, 0.0f); // Translate to the origin before doing rotation if (angle != 0.0f) { Matrix::Translate(matrix, xalign, yalign, 0); Matrix::Rotate(matrix, angle, 0, 0, 1); Matrix::Translate(matrix, -xalign, -yalign, 0); } // Expand square to image size Matrix::Scale(matrix, width, height, 1.0f); </code></pre>

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
