Images are incorrectly centered at some window sizes #40

Closed Oddwarg closed 2 years ago

Oddwarg commented 2 years ago

Small images appear blurry at some window sizes because the image centering logic at TacentView.cpp line 975 is incorrect. This can be fixed by replacing the block with the following:

float offsetW = tMath::tRound((draww - w) / 2.0f);
left    += offsetW;
right   = left+w;

float offsetH = tMath::tRound((drawh - h) / 2.0f);
bottom  += offsetH;
top     = bottom+h;

Blurry, incorrect: blurry Clear, correct: correct
